Current Behavior & Steps to Reproduce

Error: UPGRADE FAILED: failed to create resource: ConfigMap "netbox" is invalid: [data[extra-%!s(int=0).yaml]: Invalid value: "extra-%!s(int=0).yaml": a valid config key must consist of alphanumeric characters, '-', '_' or '.' (e.g. 'key.name',  or 'KEY_NAME',  or 'key-name', regex used for validation is '[-._a-zA-Z0-9]+')

the extraConfig keys are now in invalid format: extra-%!s(int=0).yaml: |- , not sure what they were before.

Seems related to #405 @LeoColomb
