Error message does not help identify the underlying cause

I have an openapi json file generated using springdoc.

I used openapi-markdown to generate the markdown file.

After I modified the spring boot project (significantly) the markdown generation fails. I suspect some of the generated documentation is not to its liking, but I cannot pinpoint what could be the issue. I saddly cannot provide the source file, as it is an internal proprietary API.

Is there a way to indicate what part of the input json made it fail?
