[karate]: retrieve an id in the response of a query and then reuse it in the next

Question

I have a problem recovering an id at the end of executing a very simple request 1 of this type:

Given path "blah"
And header Authorization = "Bearer " + token
And request req
When method post
Then status 201

* def ts_id = response.id

Most of the time I recover the ts_id well, but I have the impression that this is not always the case. Thus the request 2 which follows the request 1 and which needs the ts_id returns an error 400.

The request 2 fails:

Given path 'toto', ts_id, 'tata'
And header Authorization = "Bearer " + token
And request req
When method post
Then status 200

Here'es the following error:

status code was: 400, expected: 200, response time in milliseconds: 118, url...

My test is very simple and has no overlap or external call I don’t know how to deal with this random problem. Thanks for help

Most likely this is because your first response is changing. There is no way to troubleshoot this unless you provide a way to replicate. Let me say that it is highly unlikely to be an issue with Karate.

That said, see if retry until is the solution for your problem: https://stackoverflow.com/a/55823180/143475
