How to fix 504 gateway timeout issue in nifi?

Explorer

Hi,

 

I am using InvokeHTTP processor to invoke one API (this api functionality is to access data from 2 tables, does some data manipulation/operation and finally dumps the data to 3rd table, and returns response message " Data Inserted" back to NIFI)

 

When checked at the postman local machine this API retruns the response in 30secs

 

But when checking the same at Nifi InvokeHTTP processor end, I am getting 504 Gateway-Timeout error, and routed to retry state, then failure state. Meanwhile when checked at the cassandra end, data got dumped successfully

 

Could anyone please help to resolve this issue.
