The error is intermittent and the same request works for the next time.

@Atanu Mazumdar , Most probably it's an issue with one of the Message Processor or router. Please work with Apigee Support. Community has limited access to information when it comes to above generic error. Keep us posted if any.

@Anil Sagar

,Below were the logs from message processor which were shared by apigee support team

org:honeywell env:aero-prod api:SIGNS-getFile-V1 rev:4 messageid:rrt-0308479c56e3b8191-d-ea-8122-1797417-1 NIOThread@2 ERROR ADAPTORS.HTTP.FLOW - AbstractResponseListener.onException() : AbstractResponseListener.onError(HTTPResponse@58a24035, should start with 'HTTP/', but given string is:trueHTTP/1.1)

Can you please help me in understanding this? To reiterate same request goes through successfully the next time. Its random.

Can you run a tcpdump while running the traffic (if it is reproducible) & evaluate the issue.

tcpdump host <<target host>> and port <<port_number>> -w dump.out

Not applicable

I see the same issue, anyone we can contact?
There was a service disruption, and they are saying its fixed, but apis are still not working.
