Fon which trigger did you add the action? and how did you configure it?
F@stebenz @adlerhurst can you help here?
FOne more question, is the name of your action the same as the name of the function in your script? in your case add_metadata?
AWhich endpoint did you call or what did you click in the ui?
AOkay, did you create the users in the console or self register?
Acan you try to run the action on pre creation?
Aand the user itself will not see the the metadata. You need to log in using an admin to see the metadata
Aplease let us know if it worked or if you still have trouble
