My usecase is that I want to execute the subprocess n number of times, where, n = number of items in the list. For each item, call doc verification service is called which in turn calls an external api. I need to wait for the response. When the response is received, throw a message signal and then update data. If no response received within 2 minutes, again, update data. The subprocess execution should be in parallel.
The problem I'm facing is that I'm unable to throw a message signal from java code (call doc verification service). When I query, it gives null always.
