The metadata validation using the Regular Expression works pretty good, but has some room for improvement.
For example, if the pattern does not match, a generic error “Metadata type validation error; The input string does not match the pattern.”
There is no indication to the user of what field is throwing the validation error. Would it be possible to pass another argument in the Regular expression validator. For example:
pattern: ^[0-9]{7}$
error_message: "Employee ID Must be 7 digits"
