HTTP Post gave error if there is 0 input recodes - pentaho

I am trying to use the HTTP Post if there is a record in the precursor step, but if there are 0 records in precursor step it's giving an error.
HTTP Client New.0 - Error finding field [xxxxx] !
Is there any way to handle this error or don't perform the HTTP Post step if a precursor step doesn't have any records.

I am in the opinion of Cristian Curti that the error does not come from empty stream but a bad configuration of your POST step.
However, just in case, you have a Detect empty stream step, documented here, with a simple example.

Unable to POST NZ employee openingBalances to Xero?

I am attempting to create a single opening balances record against an existing employee but keep getting a 400 Bad Request response with this detail...
At least one NZ opening balance item is required in the request
I am following the instructions as per this documentation...
https://developer.xero.com/documentation/api/payrollnz/employeeopeningbalances#post-opening-balances
URL : {DestinationID} is properly replaced with the employee GUIDhttps://api.xero.com/payroll.xro/2.0/employees/{DestinationID}/openingBalances
JSON Body[{"periodEndDate":"2011-01-30T00:00:00","daysPaid":5.00,"unpaidWeeks":0.00,"grossEarnings":1442.31}]
The Xero forums and support is pretty unreliable so I'm posting here in the hopes for a better response.
After some trial and error using the API Explorer that Xero provides I was able to get it working using their example....
I eventually learned that daysPaid and unpaidWeeks must both be integer whole numbers or else it fails.... The error message provided is misleading but this resolves the problem.

Http status code when data not found in Database

I'm trying to understand which Http Status Code to use in the following use case
The user tries to do a GET on an endpoint with an input ID.
The requested data is not available in the database.
Should the service send back:
404 - Not Found
As the data is NOT FOUND in the database
400 - Bad Request
As the data in the input request is not valid or present in the db
200 - OK with null response
200 - OK with an error message
In this case we can use a standard error message, with a contract that spans across all the 200 OK responses (like below).
BaseResponse {
Errors [{
Message: "Data Not Found"
}],
Response: null
}
Which is the right (or standard) approach to follow?
Thanks in advance.
Which is the right (or standard) approach to follow?
If you are following the REST API Architecture, you should follow these guidelines:
400 The request could not be understood by the server due to incorrect syntax. The client SHOULD NOT repeat the request without modifications.
It means that you received a bad request data, like an ID in alphanumeric format when you want only numeric IDs. Typically it refers to bad input formats or security checks (like an input array with a maxLength)
404 The server can not find the requested resource.
The ID format is valid and you can't find the resource in the data source.
If you don't follow any standard architecture, you should define how you want to manage these cases and share your thought with the team and customers.
In many legacy applications, an HTTP status 200 with errors field is very common since very-old clients were not so good to manage errors.

How to check if all status codes are 200 in Mulesoft 4?

Say for example, I created a flow for scatter-gather and I want to check if all endpoints are returning same result status code 200 or throw an error if not.
Configure the Response Validator (General > Response > Response Validator) for each HTTP Request so only 200..299 responses are considered valid.
You can use try block for every HTTP request on wrap whole scatter gather. If one fails, capture HTTP status code in on error propogate and log the results.
I suggest you wrap each request into try block, if you already have a global error handler defined, it should pick up status code 500 etc. Otherwise, capture response code into dataweave

Counting the number of response codes in JMeter 4.0

I run some load tests (all endpoints) and we do have a known issue in our code: if multiple POST requests are sent in the same time we do get a duplicate error based on a timestamp field in our database.
All I want to do is to count timeouts (based on the message received "Service is not available. Request timeout") in a variable and accept this as a normal behavior (don't fail the tests).
For now I've added a Response Assertion for this (in order to keep the tests running) but I cannot tell if or how many timeout actually happen.
How can I count this?
Thank you
I would recommend doing this as follows:
Add JSR223 Listener to your Test Plan
Put the following code into "Script" area:
if (prev.getResponseDataAsString().contains('Service is not available. Request timeout')) {
prev.setSampleLabel('False negative')
}
That's it, if sampler will contain Service is not available. Request timeout in the response body - JMeter will change its title to False negative.
You can even mark it as passed by adding prev.setSuccessful(false) line to your script. See Apache Groovy - Why and How You Should Use It article fore more information on what else you can do with Groovy in JMeter tests
If you just need to find out the count based on the response message then you can save the performance results in a csv file using simple data writer (configure for csv only) and then filter csv based on the response message to get the required count. Or you can use Display only "errors" option to get all the errors and then filter out based on the expected error message.
If you need to find out at the runtime then you can use aggregate report listener and use "Errors" checkbox to get the count of failure but this will include other failures also.
But, if you need to get the count at the run time to use it later then it is a different case. I am assuming that it is not the case.
Thanks,

jmeter help - test around polling /w meta refresh

I am new to jmeter and am working on putting together a test plan. The hurdle I've encountered is as follows:
First, a POST is made to processForm.aspx
Then, the user is redirected to pleaseWait.aspx
This page either redirects immediately to results.aspx OR loads, with a META REFRESH tag set to refresh in 5 seconds (and this step is repeated).
Now -- I can get this to execute by doing the following:
HTTP Sampler POST to processForm.aspx
Assert Response contains "<something on pleaseWait.aspx>"
While LAST
HTTP Sampler GET to pleaseWait.aspx
Assert Response contains "<something on results.aspx>"
However -- I don't care for this method, because it results in failed assertions (even though things are working as expected). I am sure there must be some other way to do this? Anyone more familiar with JMeter than I?
UPDATE:
Got it going by using Regular Expression Extractor instead of Assertions.
1) Add a User Defined Variables section at Test Plan Root
2) Add a variable to it "LoginWait" and "false"
HTTP Sampler POST to processForm.aspx
RegEx Extract Response Body contains "<something on pleaseWait.aspx>" into LoginWait
While ${LoginWait}
HTTP Sampler GET to pleaseWait.aspx
RegEx Extract Response Body contains "<something on pleaseWait.aspx>" into LoginWait
...
You could try using "follow redirects" on your HTTP Request. It would eliminate the logic you need, and still get you to the page you're going.
