The issue occurs because there has been some failure in setting your default task list, hence it is unable to get your tasks. It ideally should work out-of-the-box, but it seems the request to fetch your task list has failed due to some reason?
But ideally, it should fetch for the task-list once again if the default task-list is not set which is clearly not happening.

Could you please log out using rchore google logout and retry once more? This would clear the db.

Thanks! That Fixed It! But I had to manually tick the option to give permission to Google Tasks.

[DarthBenro008]

Makes sense that it was an oauth issue, this can be handled using scope checks with the result from the oauth token itself.

Also, Could you please let me know where you had tick things manually?

First and formost , we have to remove this warning --> It can make user's skeptical about the app.

The screen where I had to manually tick for giving permission for Google Tasks.

Unfortunately, I cannot remove the screen because the Create and edit scope of Google Tasks is considered a "sensitive scope" by Google and the app will have to go through manual verification by Google Team which may incur a cost. I might send the app for verification after the "Google Calendar" feature is implemented in rChore that is set for its v1.0.0 release.

The screen where I had to manually tick for giving permission for Google Tasks.

Thanks for sharing! There is no way to bypass this due to Google's strict OAuth norms to protect user privacy and data. However, I think there might be a query param that we can send so that the checkbox is selected by default.
