@vinay-sethi Well, the problem was not in micronaut openapi, but in your code. You specified an incorrect value in the schema type. Micronaut openapi was not ready for such crooked data :-)

But I agree that such a situation should be handled more correctly. I added a check and next time you will see this message:

Error reading Swagger Schema for element [id]: {"type":"query"}

@altro3 thanks for pointing that out. the same code working in 6.12.2 is what threw me off.
