I have this error in Facebook ads: The parameter creative_sourcing_spec['website_summary_spec']['action_metadata']['type'] is required. (#100) CAN ANYONE SOLVE IT?

Youre missing a required field in your ad setup. Double check your creative specs and make sure (action_metadata.type)
is filled in without it, Facebook wont know what action your ad is for.
