[huynguyennovem]

For those who got this error (this burns my few hours, LOL). Adding more detail from @lhhuu 's answer.
Make sure you set domain or domain has full path with http or https
EG:

http://abc.xyz

[normancarcamo]

As an improvement the error could detail that the issue is related to the domain scheme, let me know if you cannot add it to do so by my self.

For me it was because after adding dependency I did not reinstalled the whole app
