Answer 1

There is likely a hidden character among your code. Copy your code and paste it into a plain text editor and remove any junk text.
If you are using Visual Code you can turn on "Render whitespace".
Press CTRL + SHIFT + P / CMD + SHIFT + P and serach for "Render whitespace" and toggle it on

Update......I solved my Problem by Downgrading the Firebase-admin Version
npm i firebase-admin#10.3.0
