Receiving error when creating new trigger on Apps Script

Question

Receiving this error when trying to create a new trigger "Script authorization failed. Please check your pop-up blocker settings and try again."

Have attempted to allow this site to accept pop ups and even turning off the pop blocker but it hasnt made a difference. Anyone have a fix?

Answer 1

I encountered the same problem and managed to fix it by first manually executing my script from the script editor and granting the necessary permission at that stage, and then adding the trigger.
