WSO2 Invalid request line

Question

I have REST API which is made based on this tutorial: https://ei.docs.wso2.com/en/latest/micro-integrator/use-cases/tutorials/sending-a-simple-message-to-a-datasource/ I have been able to propagate this API to API manager from micro integrator. But when I try to call it from API manager, I get response

{ "code": "101500", "type": "Status report", "message": "Runtime Error", "description": "Error in Sender" }

I have also created Configs and metadata for this API. But when I try to call my API I get this error at micro integrator.

Answer 1

This kind of error is observed when we send HTTPS requests to the HTTP Listener of the Micro Integrator. The Micro Integrator uses two ports for HTTP (default 8290)and HTTPS(default 8253) connections. If we send an HTTPS request as follows to port 8290 a similar error is observed.

curl -X POST "https://localhost:8290/hello/send" -k

Therefore could you check the endpoint URLs in the API manager and do the needful?
