Invalid firebase url specified Error

When screen initilize I am set firebase url ,token and project bucket in block section .And it Will show Invalid firebase url specified but works perfectly.if i set firebase url in designer section then it can’t show any error.

How to solve this error?

check again there must be something wrong in your data,check again everything ,

All Work perfectly and data no error but show this error. And i can’t remove firebase token in designer page.firebase url and project bucket removed but token can’t remove .why this problem ?

use another component of firebase, like if you have used firebase database1, try to add firebase database2 and try to shift all work on that
