Hi @comat0zz. Thank you for reporting this. It seems to be caused by the fact the the Swagger 2 parser was not included in the generated linux native image. Can you please confirm if your API spec is swagger 2? If this is true, the fix is available in https://github.com/Endava/cats/commit/58a338e6961ac192c5775799cb80797f8b677160 and will be released in 7.0.2.

comat0zz commented 2 years ago

Yes, "swagger": "2.0"

en-milie commented 2 years ago

Great. The fix will be available in 7.0.2, which will be released this week.

tasoskoutlis-f3 commented 2 years ago

Hi @en-milie I just got the 7.0.2 version, I have a Swagger 2 file and I am still getting the same error

Hi @daniel-f3. Can you please post a sample that fails? I'm not able to reproduce this anymore with the swagger 2 spec I have.

en-milie commented 2 years ago

Should be (finally) fixed now in https://github.com/Endava/cats/releases/tag/cats-7.0.4

daniel-f3 commented 2 years ago

Awesome thank you, it is fixed.
