Would anyone be able to post a stack trace of the exception? It's not reproducible for me.

[andreasevers]

Could it be that this conflicts with the bundled OpenApi Specification plugin?

[asaarilahti]

Could someone confirm this still occurs with version 1.3.0?

[aurelien-baudin]

Hello, I still have this issue with version 1.3.0
