Spring Cloud Openfeign Failed to convert ResponseEntity object

Hello, when invoking a remote method that returns a "responseEntity" object, the following error occurs:

java.io.IOException: Incomplete output stream

Hello, @eduardosilvaneto, thanks for submitting the issue. Please learn how to properly format code and logs. It does not seem that the issue is in SC OpenFeign - there's problem processing the input stream with Java methods, the response might be corrupt. In any case, I can take a closer look at this for you, anyway, but in order to get this done, please, upgrade to 2021.0.0 (2020.0.x is no longer supported) and provide a minimal, complete, verifiable example that reproduces the issue.

Thank you very much for your feedback. I really had something corrupting the file, maybe my VPN. Performing the test with the same code worked.
