Nifi/Minifi: Failed because FlowFile had an "http.context.identifier" attribute of but could not find an HTTP Response Object for this identifier

Question

I'm using Nifi 1.7.0 to create a flow and then I convert it to Minifi 0.5.0. When I run the application, initially it runs well, but after some requests I'm getting 504 error (SERVICE_UNAVAILABLE), with this error message in minifi-app.log:

Failed to respond to HTTP request because FlowFile had an "http.context.identifier" attribute of but could not find an HTTP Response Object for this identifier.

I am using the same StandardHttpContextMap controller service for processors HandleHttpRequest and HandleHttpResponse, and I have also increased the Request Expiration parameter.

It seems that this issue only occurres when I increase the number of threads. With just one thread, it runs without any errors.

Has anyone faced the same issue?

I'm facing the same thing, Ricardo. Did you happen to solve it? — Bob Haffner, Aug 23 '21 at 14:20

The HandleHTTPRequest and HandleHTTPResponse need to use the same HTTP Context Service

Both processors are already using the same HTTP Context Service – Ricardo Aug 16 '21 at 17:28
Then you need to provide more infomation about your flow and configs - this is not enough information to go on. – Sdairs Aug 16 '21 at 18:51
I edited the question just now, with more informations about it – Ricardo Aug 17 '21 at 17:01
