I have followed all the steps from
https://docs.frappe.io/erpnext/user/manual/en/google_calendar
and
https://docs.frappe.io/erpnext/v13/user/manual/en/erpnext_integration/google_settings
to setup Google Calendar Integration.
I have set this as Authorized redirect URIs
https://erp.example.com?cmd=frappe.integrations.doctype.google_calendar.google_calendar.google_callback
However, I can’t authorize access to G calendar.
This gives an error:
It asks to set the following redirect uri.
Its the same that I have set.
Still, I am getting Error 400: redirect_uri_mismatch
