Though I have defined the integration when I try to deploy an api gateway I keep getting "No integration defined for method" error similar to https://stackoverflow.com/questions/46087890/no-integration-defined-for-method-choose-a-stage-where-your-api-will-be-deploy?rq=1
Here they have mentioned the reply as "Set up the integration method".
However I have set up integration method. Attaching a screenshot, so what exactly is the problem in my case?
