Unexpected value 'type changed'

[Serginyu]

Hello! I have encountered the following error few days ago Unexpected value 'type changed', the changes
I've been researching and can't find the problem.

Tested versions of the library in which this error occurs (@1.30.0/@1.26.0)

Would you know why this can happen?

Output:

This tool uses a Bitbucket Cloud Rest Client:
https://github.com/tomasbjerre/bitbucket-cloud-java-rest-api

That client is generated from Openapi specification:
https://github.com/tomasbjerre/bitbucket-cloud-java-rest-api/blob/master/get-swaggerjson.sh

If I:

• download that spec
• convert it to Openapi: https://editor.swagger.io/
• rename it to https://github.com/tomasbjerre/bitbucket-cloud-java-rest-api/blob/master/openapi.yml
• And run ./gradlew openApiGenerate -s it will fail. I added a PR to make the failure clearer, but the problem is in the specification. The specification is not valid!

Possible solution might be to find another java Bitbucket Cloud rest-client to use here in this tool...
