Header definitions are overriding others

[hirth-abi]

Describe the bug

When multiple @AsyncOperations with @Headers are defined, only one of them will be used for all.

Se my reproducer project where different header values should be shown:

Additionally in the old UI a strange schema with "undefined-title" is shown for it:

Hi @hirth-abi,
have you tried adding the schemaName in AsyncOperation.Headers?
(Validation for the field is added in #896 )

The alternative would be to auto-generated a schemaName, like <channelName>-<hash-of-headers>. Do you have thoughts on this?

[hirth-abi]

Yes, that works if the schema is different and defining the schema name in a meaningful non-generated way seems to be better 👍 (it just looks a bit strange - although technically correct - to have a different header schema per message, just because the same standardized header is sent with a different value)

[github-actions]

The change is staged for release and will be part of the next release.

If you want to try and verify it in your application today,
use the latest 1.X.0-SNAPSHOT build as described in our README.md > Testing SNAPSHOT version

Thank you for the report/contribution!
