Invalid URL Generation Due to Invalid Character in Path

[leonardo-zup]

Describe the bug

The line 3304 of the file kubernetes/src/main/java/io/kubernetes/client/openapi/apis/CustomObjectsApi.java:

3304 │ ········String localVarPath = "/apis/{group}/{version}/{plural}#\u{200e}"

is causing the generation of an invalid URL. The inclusion of #\u{200e} at the end of the URL path results in an invalid or improperly formatted URL.

I don't see this in the code at release-22

https://github.com/kubernetes-client/java/blob/release-22/kubernetes/src/main/java/io/kubernetes/client/openapi/apis/CustomObjectsApi.java

Do you have a link to the commit where you see this code?

Either way, this comes out of the open API spec so if there is a bug, it needs to be corrected in that spec.

Given that HEAD looks ok:
https://github.com/kubernetes-client/java/blob/master/kubernetes/src/main/java/io/kubernetes/client/openapi/apis/CustomObjectsApi.java#L3304

I don't think that there is any action needed here, but let me know if there is more to do.

On the screenshot you can see the #

The hidden char you can only see downloading the code and using bat -A CustomObjectsApi.java or something similar

This was introduce from the swagger model here ^ so it will impact all language clients we have. Will send a PR to fix the model first..

Thanks @yue9944882. Yeah we'll need to fix that spec file first and then regenerate the code.
