Description

Why make a strong intercept of failed responses? I need to get the response code for the expected failure, but it will be intercepted internally, causing an error to be reported before I get the response error code

The report identifies python-nextgen v6.5.0 but provides no OpenAPI declaration, generation details, reproduction steps, files, or tests. Start by obtaining a minimal reproducible specification and generation command, then trace how the generated client handles the expected failure response. Done means the expected response code can be obtained without an internal interceptor reporting the failure first.
