Malformed URL Error when authenticating with a Google Family Link Supervised Account

[N0tACyb0rg]

The problem

Due to being under the age of 18, my Google account is supervised with Google Family Link by my parents. When trying to log in with my account to enable the Google Drive integration, I get a malformed URL error from Google after one of my parents signs in to give their approval for the authentication process to continue.

I have already set up a Google Cloud project as I have the Google Home (exposing HA to Google Home) and the Google Calendar integrations set up. Additionally, if signing in with a non-Family Link supervised account (as a test with approval from my parents), this error does not occur, and I get the normal consent screen for allowing HA access to Google Drive.

This may not necessarily be an issue with Home Assistant itself, but what could be done to resolve this issue?
