Description

Description

Produced by codegen Python code does not support handling of exceptions in anync mode (with callback). If swagger client code raises exeption, callback will never be called.

Swagger-codegen version

5

Command line used for generation

-l python

Suggest a Fix

Catch all exceptions in generated swagger client and return special type of result in case of exceptions.

Contributor guide

Research direction
Examine the generated Python async client code to identify where exceptions are raised without being caught. Implement a result wrapper that captures exceptions and delivers them via the callback.
