MMM-MicrosoftToDo - invalid_grant
I’ve installed the “MMM-MicrosoftToDo” module following the instructions provided.
Entered the relevant details in the config.js
And I get no tasks just a message saying:
“ Error occurred invalid_grant. Check logs.”
Anybody any idea what this means ?
Or where log files are ?
Thanks in advance
Had the same issue my solution was to go back and regenerate a new Auth Code and subsequent new Refresh Token.
I remember a logfile stating this has expired.
My take is:
- Client ID is permanent
- Client Secret is permanent
- Auth Code expires
- Refresh token will not work if the included Auth Code has expired
