It happens when exporting to the google calendar

Sorry, I can't submit images when I'm logged in (because it just says "Something went wrong, please try again later." and my comments kinda automatically get submitted when I login even if I can't see the post lmao) The entire error message I get when trying to export to Google Calendar is:

You can’t sign in because this app sent an invalid request. You can try again later, or contact the developer about this issue. Learn more about this error

If you are a developer of this app, see error details.

Error 400: redirect_uri_mismatch

You can't sign in to this app because it doesn't comply with Google's OAuth 2.0 policy.

If you're the app developer, register the JavaScript origin in the Google Cloud Console.
