With each modification that I make, I execute the compilation and deploy to the Goerli testnet.
Now, it's complaining that I have 5 similar contracts and it's giving an error when checking.
What to do?

How do I compile a new function created inside a package in plsql, to see syntactical error and so on
You can't compile a single function - compile the whole package.
If your concern is about invalidating the whole package in case that function has errors, then
create a standalone function (i.e. outside of the package)
debug it
once it is OK (doesn't have syntax errors, returns result as expected), include it into the package
In addition to #Littefoot's advise I'd say: use a proper GUI. Oracle has a free tool called sql developer. It has a great interface for editing database objects (packages/functions/procedures/triggers). It highlights errors and is very well documented (https://www.thatjeffsmith.com/sql-developer/). Note that is does not point out syntax errors - but once you're a bit used to working with pl/sql they become obvious very quickly.
In Oracle, after compiling a procedure/function/package. If there is an error then the command will return with the message:
ORA-24344: success with compilation error
You can then use:
SHOW ERRORS
or
SELECT * FROM USER_ERRORS;
or, for example, for errors with packages in a specific schema:
SELECT *
FROM ALL_ERRORS
WHERE owner = 'SCHEMA_NAME'
AND type IN ( 'PACKAGE', 'PACKAGE BODY');
Which will list the errors (complete with line numbers and error messages) and you can then debug the procedure/function/package and recompile it.

When attempting to make a call to a program compiled with #solana/solidity, I'm getting the following error:
Transaction simulation failed: Error processing Instruction 0: Program failed to complete
Program jdN1wZjg5P4xi718DG2HraGuxVx1mM7ebjXpxbJ5R3N invoke [1]
Program log: pxKTQePwHC9MiR52J5AYaRtSLAtkVfcoGS3GaLD24YX
Program log: sender account missing from transaction
Program jdN1wZjg5P4xi718DG2HraGuxVx1mM7ebjXpxbJ5R3N consumed 200000 of 200000 compute units
Program failed to complete: BPF program Panicked in solana.c at 285:0
Program jdN1wZjg5P4xi718DG2HraGuxVx1mM7ebjXpxbJ5R3N failed: Program failed to complete
jdN1wZjg5P4xi718DG2HraGuxVx1mM7ebjXpxbJ5R3N is the program's public key and pxKTQePwHC9MiR52J5AYaRtSLAtkVfcoGS3GaLD24YX is the sender's public key.
I'm using a fork of the #solana/solidity library that exposes the Transaction object so that it can be signed and sent by Phantom Wallet on the front end. The code that results in the error is as follows:
// Generate the transaction
const transaction = contract.transactions.send(...args);
// Add recent blockhash and fee payer
const recentBlockhash = (await connection.getRecentBlockhash()).blockhash;
transaction.recentBlockhash = recentBlockhash;
transaction.feePayer = provider.publicKey;
// Sign and send the transaction (throws an error)
const res = await provider.signAndSendTransaction(transaction);
I would attempt to debug this further myself, but I'm not sure where to start. Looking up the error message hasn't yielded any results and the error message isn't very descriptive. I'm not sure if this error is occurring within the program execution itself or if it's an issue with the composition of the transaction object. If it is an issue within the program execution, is there a way for me to add logs to my solidity code? If it's an issue with the transaction object, what could be missing? How can I better debug issues like this?
Thank you for any help.
Edit: I'm getting a different error now, although I haven't changed any of the provided code. The error message is now the following:
Phantom - RPC Error: Transaction creation failed. {code: -32003, message: 'Transaction creation failed.'}
Unfortunately this error message is even less helpful than the last one. I'm not sure if Phantom Wallet was updated or if a project dependency was updated at some point, but given the vague nature of both of these error messages and the fact that none of my code has changed, I believe they're being caused by the same issue. Again, any help or debugging tips are appreciated.
I was able to solve this issue, and although I've run into another issue it's not related to the contents of this question so I'll post it separately.
Regarding my edit, I found that the difference between the error messages came down to how I was sending the transaction. At first, I tried sending it with Phantom's .signAndSendTransaction() method, which yielded the second error message (listed under my edit). Then I tried signing & sending the transaction manually, like so:
const signed = await provider.request({
method: 'signTransaction',
params: {
message: bs58.encode(transaction.serializeMessage()),
},
});
const signature = bs58.decode(signed.signature);
transaction.addSignature(provider.publicKey, signature);
await connection.sendRawTransaction(transaction.serialize())
Which yielded the more verbose error included in my original post. That error message did turn out to be helpful once I realized what to look for -- the sending account's public key was missing from the keys field on the TransactionInstruction on the Transaction. I added it in my fork of the #solana/solidity library and the error went away.
In short, the way I was able to debug this was by
Using provider.request({ method: 'signTransaction' }) and connection.sendRawTransaction(transaction) rather than Phantom's provider.signAndSendTransaction() method for a more verbose error message
Logging the transaction object and inspecting the instructions closely
I hope this helps someone else in the future.
I'm trying to follow a tutorial to create an NFT: https://ethereum.org/en/developers/tutorials/how-to-write-and-deploy-an-nft/
I took a faucet here: https://faucet.metamask.io/
But when trying to mint the contract I get this error:
λ npx hardhat --network ropsten run scripts/deploy.js Error: insufficient funds for intrinsic transaction cost (error={"name":"ProviderError","code":-32000,"_isProviderError":true}, method="sendTransaction", transaction=undefined, code=INSUFFICIENT_FUNDS, version=providers/5.5.3) at Logger.makeError (E:\chat\nft\my-nft\node_modules\#ethersproject\logger\src.ts\index.ts:225:28) at Logger.throwError (E:\chat\nft\my-nft\node_modules\#ethersproject\logger\src.ts\index.ts:237:20) at checkError (E:\chat\nft\my-nft\node_modules\#ethersproject\providers\src.ts\json-rpc-provider.ts:53:16) at E:\chat\nft\my-nft\node_modules\#ethersproject\providers\src.ts\json-rpc-provider.ts:215:24 at processTicksAndRejections (internal/process/task_queues.js:93:5) { reason: 'insufficient funds for intrinsic transaction cost', code: 'INSUFFICIENT_FUNDS', error: ProviderError: insufficient funds for gas * price + value at HttpProvider.request (E:\chat\nft\my-nft\node_modules\hardhat\src\internal\core\providers\http.ts:49:19) at LocalAccountsProvider.request (E:\chat\nft\my-nft\node_modules\hardhat\src\internal\core\providers\accounts.ts:182:36) at processTicksAndRejections (internal/process/task_queues.js:93:5) at EthersProviderWrapper.send (E:\chat\nft\my-nft\node_modules\#nomiclabs\hardhat-ethers\src\internal\ethers-provider-wrapper.ts:13:20), method: 'sendTransaction', transaction: undefined } I have tried to find on the net I do not understand why it does not work when I am on the ropsten test network.
how i can solve this problem?
Thank you
I also had the same problem, and I reached the same point in that tutorial failing with the same exact message.
The problem on my side was the address was indeed without funds.
Go to this address to request funds from the faucet https://fauceth.komputing.org/ and enter your wallet address from metamask. if you have the browser extension you can find your correct address right there, see the following image:
You can also check on Etherscan to validate if the funds are really there in your address.
Hope it helps Rija Cloud !
Make sure you select rospten network in Alchemy.
Make sure when you update your testnet eg: from rinkeby to kovan, you also go ahead and get the new URL to reflect that change in network. If you done the URL will be pointing to the wrong testnet.
I am trying to run the example "optaplanner-mixedvrp-experiment" developed by Geoffrey De Smet and when I run it it throws me the following error:
Caused by: java.lang.IllegalStateException: The entity (MY) has a
variable (previousStandstill) with value (MUNO) which has a
sourceVariableName variable (nextVisit) with a value (WERBOMONT) which
is not null. Verify the consistency of your input problem for that
sourceVariableName variable.
I have not made any change, I have only cloned and executed it, I import and solve it and it throws me this error.
Do you know what could be happening?
I am applying it in the development of a variant of VRP with multiple deliveries and collections, but it throws me the same error. I have activated the FULL_ASSERT mode and nextVisit, previousStandstill, visitIndex are always null
It's been a long time since I looked at that code, so it's using an old version of optaplanner. Our goal is still to clean it up and offer an out of the box example for VRPPD (and probably remove some boilerplate along the way, using the upcoming #CollectionPlanningVariabe etc). That being said, we have multiple users&customers who used that optaplanner-mixedvrp-experiment to successfully build VRPPD implementations.
Which dataset did you try?
FWIW, that IllegalStateException says that when A.previous = B, the B.next is not A. So either the dataset importer didn't import it correctly - before calling solve() - especially if it fails before the first CH step in FULL_ASSERT. Or one of the custom moves corrupted the model.
When I hit a breakpoint in a VLAB script, how can I find out if I have caused elaboration to finish or not, yet?
My script reaches a statement that raises an error:
Error: (E529) insert module failed: elaboration done
(The command that causes this is vlab.instantiate("stim", "stim"))
So obviously elaboration was unexpectedly (for me) already completed. I need to somehow go back in the process and find out where that happened - so I need some way of asking "is elaboration complete?" at the point where I set breakpoints earlier in the script.
SystemC provides the following function to query the current phase of elaboration or simulation.
sc_status sc_get_status();
It returns either SC_ELABORATION, SC_BEFORE_END_OF_ELABORATION, SC_END_OF_ELABORATION, SC_START_OF_SIMULATION, SC_RUNNING, SC_PAUSED, SC_STOPPED, or SC_END_OF_SIMULATION.
See section 4.5.8 in the SystemC Language Reference Manual for more details. Note that this function was only added in the most recent version of the standard, IEEE Standard 1666-2011.
In VLAB, the SystemC API is available from the sysc Python package, so the following script can be used to test if the current phase is at elaboration:
import sysc
print "Is elaboration phase:", sysc.sc_get_status() == sysc.SC_ELABORATION
