@roycaihw Any plan to fix this? Thanks.

[pingsutw]

@jinchihe I got the same problem, did you solved it?

[jinchihe]

@pingsutw I pined to old kubernetes python sdk to work around that.

kindly ping @roycaihw , any updates for this? Thanks!

Thanks, it works for me

Add this to the api_client line ~215, solved the issue for now.
elif isinstance(obj, property):
return None

hello @roycaihw and all,

I found the problem still exists in 12.0.0, any plan to fix the problem? this is a block issue. Thanks.

[jinchihe]

Seems that's cuased by kubernetes client use openapi_types instead of swagger_types from 11.1?

Need to update the generate openapi_types for the crd before calling k8s client.
Close the ticket. Thanks.

[roycaihw]

Sorry for the late response. Yes we've switch the code generator from swagger codegen to openapi generator, and the attribute was renamed from swagger_types to openapi_types. If you generated models for your custom resources, you need to regenerate them using openapi-generator. You could also use the dynamic client to access custom resources, which do not have this issue.

Yeah, I already did that. Thanks.

@roycaihw
I am simply using

client.CoreV1Api().create_namespaced_secret
client.CoreV1Api().create_namespaced_config_map

method and this method also has this issue in version 11.0.0 and 12.0.0. Note that these are not custom resources.
