REST API null in User Registration Confirmation Email

I am testing the User Registration Confirmation Email by adding a new user through the console. I am receiving the email yet the link in the email has “null” as the REST API, therefore the confirmation fails. If i replace null with the REST API on the link, the confirmation works. Now, why is the REST API not automatically added to the link?

APP ID is 2D8284EF-2DE3-E45A-FF7E-AA6451483000

Never mind this question. I tried through the actual app and the RESP API is provided in the email. It just doesn’t if the user is created manually through the console.
