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