Seeing parsing errors in Swagger UI but not seeing with generated json

Hi there,

We are trying to migrate from spring fox to spring doc as the former is no longer compatible with the latest spring boot version ( 2.6.x) and spring doc internally used open API specification ( 3.0.1). So I thought this might be the correct forum to raise the issue.

We have made all the migration changes and everything is working perfectly in my local but when we try to deploy to one of our ec2 instances we are facing the below issue. The swagger validator badge is invalid.

And on clicking the Invalid Json symbol we are getting the below error message,

I have fetched my swagger JSON file ( from the v3/api-docs) and checked in swagger editor it is not having any parsing errors, it just has a couple of semantic errors ( delete method expecting a request body ) can anyone point me to the reason we are getting it or tell me how to get more details on the issue?

Start by comparing the Swagger JSON fetched from v3/api-docs on the EC2 instance with the version that passes in Swagger Editor, then inspect how the validator badge parses it. Check whether the reported parsing error is distinct from the noted semantic error about a DELETE request body; done means identifying a reproducible cause or a more detailed validation error.
