I was updating and testing a Stripe integrated form this evening and encountered the following validation error:
This value must match the regex pattern. (/\A[[a-zA-Z0-9_-]+\z/ does not match for the value gosubscription(annual)_4_1year_2000).
The reason for this error is that my feed, named GO Subscription (Annual), containing parentheses. Removing the parentheses and renaming the feed to GO Subscription - Annual fixed the issue.
Simply a note for those who might venture into this same territory.
