After migrating 3 months of data with success, I got this error message, which suggests to prompt it at the forum:
Error message: Error on day 2022-09-14, { “error”: { “code”: 401, “message”: "Request had invalid authentication credentials.
Expected OAuth 2 access token, login cookie or other valid authentication credential.
See https://developers.google.com/identity/sign-in/web/devconsole-project.",
“errors”: [ { “message”: “Invalid Credentials”, “domain”: “global”, “reason”:
“authError”, “location”: “Authorization”, “locationType”: “header” } ], “status”: “UNAUTHENTICATED” } }
These errors are unexpected and will likely continue every time you run the import on this day. To resolve this issue, please ask on the forums. If you can provide access to your GA account to a member of Matomo’s support team it will provide a quicker resolution.
