Hi.
> What openapi/swagger versions are supported by the zap-api-scan.py script?
At the moment (version 7 of OpenAPI add-on) supports 1.2 and 2.0.
> Could it be that I'm doing something wrong in my swagger 2.0
definition file (so ZAP can't find my URL from it)?
The first exception indicates that ZAP is not properly processing the
definition (a bug in the add-on).
Would you mind raising an issue? [1]
