Failed to get Email address from the POST ID and Meta key

Hi,
I have created a new recipe, in which the trigger is Custom post type and the action is Creating a new User, The email field is mapped to post Id and the meta key is the meta value of one of the Meta field of ACF. After setting up, i am adding a new post to my custom post type where I am adding title and Email address to Meta field, but the recipe failed to add the new user, showing error “Invalid email”. And the email field is showing empty.

Please help to fix this. It very important urgent.
