For the rest adapter I'm getting error "Error while receiving by HTTP (error code: Configuration error on Adapter-Framework(AFW)-Server, error text: com.sap.engine.interfaces.messaging.api.exception.MessagingException: com.sap.engine.interfaces.messaging.api.exception.MessagingException: com.sap.aii.adapter.rest.ejb.common.exception.HttpCallException: HTTP POST call to http://XXXXXX not successful. Bad Request)
It was working fine earlier, now there is no change from SAP side as well as third party system and all of sudden this error is appearing. I tried processing payload in other rest testing tools like SOAPUI,Postman etc. it is working fine there. Only giving error when trying through SAP PI 7.4. Scenario is ECC->PROXY->REST. Tried doing PING , Telnet etc. they're also responding from PI Server. Can you pls help on what other steps I can do to troubleshoot this error ?
I've checked SAP Note 2546089 & 2161895, they're not relevant to our issue.
