Runtime error cannot accept arguments!

I am using firebase to authenticate the user login. Firebase handles all my tokens yet when I try to bring my id token using REST api using web to another screen send me an error message.

Help me, I want to know if this is a bug of the MIT app inventor.

Not a Firebase error, not an AppInventor error. A developer error :wink:

It appears you are trying to set the firebase rest api return into a "HasMargins" property block for a label
