Path params replace broken

[ClaudiuLSH]

I'm trying to create a VirtualMachineInstance and I receive the following error:

2020-05-26 14:59:37,683 DEBUG https://10.43.0.1:443 "POST /apis/kubevirt.io/v1alpha3/namespaces/%7Bnamespace:%5Ba-z0-9%5D%5Ba-z0-9%5C-%5D*%7D/virtualmachineinstances HTTP/1.1" 404 246
2020-05-26 14:59:37,683 DEBUG response body: {"kind":"Status","apiVersion":"v1","metadata":{},"status":"Failure","message":"namespaces \"{namespace:[a-z0-9][a-z0-9\\\\-]*}\" not found","reason":"NotFound","details":{"name":"{namespace:[a-z0-9][a-z0-9\\-]*}","kind":"namespaces"},"code":404}

The call URL is not updated with a namespace.
According to this api_client.py line 122 the replace fails. If I update that line to '{%s:[a-z0-9][a-z0-9\\-]*}' % k, quote(str(v), safe=config.safe_chars_for_path_param)) the call works:

2020-05-26 15:01:31,731 DEBUG https://10.43.0.1:443 "POST /apis/kubevirt.io/v1alpha3/namespaces/nspt1/virtualmachineinstances HTTP/1.1" 201 1109
