WebRTC - getting 'malformed constraints object' - webrtc

I am using Chrome ans working on a webRTC application. I am getting an error 'malformed constraints object' in the createAnswer() for a session Description offer
pc.createAnswer(gotDescription, errorHandler, constraints);
I have tried all the options such as
constraints = {'mandatory': {
'offerToReceiveAudio': true,
'offerToReceiveVideo': true}};
constraints = {'offerToReceiveAudio': true,
'offerToReceiveVideo': true};
and with both capital and small 'o' but still the same error.
Any suggestions?

It seems in the latest Specs, the audio/video offers are not required any more in RTCOfferOptions, so you may omit that unless you want to specify the iceRestart option which default is false.

pc.createAnswer(gotDescription, errorHandler);

WalletConnect disable infura error message

I am currently developing a dapp and I am integrating walletconnect.
I use this code for connecting:
const chainId = ContractService.getPreferredChainId();
const rpc = ContractService.getRpcAddress();
provider = new WalletConnectProvider({
infuraId: undefined,
rpc: {
[chainId]: rpc,
},
});
await provider.enable();
chainId is dynamically chosen based on if the app is in development mode or not. while in development it runs on chain id 97.
RPC is the same story, it just gets the binance smart chain RPC JSON provider.
Connecting works well, but I get the following error:
Any idea on how I can fix this without making an infura account? Or is that required..
I found out what the problem was.
make sure to add a chainId to the object like this:
new WalletConnectProvider({
infuraId: undefined,
rpc: {
1: "https://RPC_URL",
},
chainId: 1
});
Then it should work without issues, you can even omit the infuraId field

WebRTC Error - Session error description: Data channel type mismatch. Expected RTP, got SCTP

I am new to WebRTC and triyng to create my first app. I have found this article https://www.tutorialspoint.com/webrtc/webrtc_quick_guide.htm and did as it was said there. The resulted app works fine if I test it in the Chrome. But when I try to test this app in 2 browser (Chrome and Mozilla) it gives me this error:
Uncaught (in promise) DOMException: Failed to execute
'setRemoteDescription' on 'RTCPeerConnection': Session error code:
ERROR_CONTENT. Session error description: Data channel type mismatch.
Expected RTP, got SCTP..
This happens when I send an offer from Mozilla client and Chrome client tries to give an answer to this offer in this part of code:
myConnection.setRemoteDescription(new RTCSessionDescription(offer));
myConnection.createAnswer(function (answer) {
myConnection.setLocalDescription(answer);
send({
type: "answer",
answer: answer
});
}, function (error) {
alert("oops...error"); //<-- this alert fires all the time
});
I have googled this and all I have found is set new RTCPeerConnection(configuration, { optional: [{RtpDataChannels: false}] }) but if I do so then when I try to send a message it says that dataChannel.readyState is not openned.
What do I do wrong? Any help appriciated!
Thanks!
Remove optional: [{RtpDataChannels: true}] and then wait for the datachannel.onopen event to fire before attempting to send messages.

Turning off Deployd dashboard authentication

I have a Deployd application that uses the standard built-in authentication to access the "DEPLOYD DASHBOARD", the one where you enter the key that is revealed by dpd showkey.
The whole website is now secured with a username/password requirement to access it.
How do I turn off the authentication required to access the deployd dashboard?
I've tried deleting the ./.dpd/keys.json file.
I haven't yet found anything useful in the docs.
This doesn't seem like the best solution, but it does do exactly what is required:
From : http://docs.deployd.com/docs/server/
Note: If options.env is "development", the dashboard will not require authentication and configuration will not be cached. Make sure to
change this to "production" or something similar when deploying.
Example
('env': 'development' has been added):
var deployd = require('deployd')
, options = {
'port': 7777,
'db': {
'host': '127.0.0.1',
'name': 'my-database'
},
'env': 'development'
};
var dpd = deployd(options);
dpd.listen();
I won't mark this as the correct answer in case there is a solution that doesn't require doing something explicitly discouraged (ie. "make sure to change [this] when deploying").

SPServices loading but not working

$().SPServices({
operation: "GetGroupCollectionFromUser",
userLoginName: $().SPServices.SPGetCurrentUser(),
async: false,
debug: true,
completefunc: function (xData, Status) {
console.log($.fn.jquery);
console.log(xData.responseXML);
console.log(xData.responseXML.xml);
}
});
I am having a problem with SPServices not working on our dev server. It works fine on prod and testing but not on dev for some reason. If I run the code above I get the following in the console.
{readyState: 0, responseXML: undefined, status: 0, statusText: "No Transport"}
I read online this can be a problem with cross domain transfers so I set the following:
$.support.cors = true;
With that I now get the following:
{readyState: 0, responseXML: undefined, status: 0, statusText: "Error: Invalid Argument"}
I think this is because the SPGetCurrentUser call is always just returning an empty string for some reason instead of the user. Has anyone seen this behavior before? What are common things that can cause SPServices to load but not be able to execute calls? Thanks for the help.
So turns out this appears to be a bug with SPServices. It appears that when you use SPServices on a site with a port number for some reason it duplicates the port number and so everything breaks. So as in my example above I did not specify the webURL and so SPServices used the current web but duplicates the port as shown here:
correct url: http://yourserver:123/sites/yoursite
SPServices: http://yourserver:123123/sites/yoursite
To fix this simply specify a site relative webURL as shown in the working code below. Hopefully this saves someone some aggravation.
var site = "/sites/yoursite";
$(document).ready(function () {
$().SPServices({
operation: "GetGroupCollectionFromUser",
userLoginName: $().SPServices.SPGetCurrentUser({
webURL: site
}),
webURL: site,
async: false,
completefunc: function (xData, Status) {
//Do stuff here
}
});
});
Thank you for your post. Actually i got statusText:"Network Error" when i try to get the user groups using jquery in sharepoint. After passing the site url to the site variable like above code. my issue got resolved.

Basic authentication with Selenium in Internet Explorer 11

I read Basic authentication with Selenium in Internet Explorer 10
And I change my register key and when I use the user and pass in the url I don't see the basic authentication popup, but actually the page is not load. I see blank page!
I see my url in the IE but nothing happened - I see white page.
Must I change somethin in IE too?
It is not possible without some workarounds.
I also needed the same feature and previous SO answer confirms, that is it either impossible or possible with high probability of failure.
One thing I learned about Protrator is not to try to make too complicated stuff with it, or I'll have a bad time.
As for the feature- I ended up making Protractor to initiate Node.js task, which use request to make the authentication and provide back the data.
Taken straight from request module:
request.get('http://some.server.com/').auth('username', 'password', false);
// or
request.get('http://some.server.com/', {
'auth': {
'user': 'username',
'pass': 'password',
'sendImmediately': false
}
});
// or
request.get('http://some.server.com/').auth(null, null, true, 'bearerToken');
// or
request.get('http://some.server.com/', {
'auth': {
'bearer': 'bearerToken'
}
});
