Description
Metadata labels must be valid and conform to the pattern ^(([A-Za-z0-9][-A-Za-z0-9_.]*)?[A-Za-z0-9])?$.
This requires label values to start and end with an alphanumeric character and may include dashes, underscores, or dots in the middle; labels that do not match this pattern are reported as IncorrectValue with the resource and label details.
