I was having the same problem - this fixed it for me:

bug…

missing data, when display is requested

do this

edit MMM-GoogleTasks.js

change line 37
from

	this.tasks;

to

	this.tasks= {};

@njw Many thanks! It works with your new update.

I’m having the same issue. Any updates?

Unable to get modules to load. Is this still being supported?

@sdetweil - Thanks for your reply. So does this mean that no new tokens can be created?

Also - attempted to authorize and obtain token directly from the Fitbit site using their token authenticator from the “OAuth 2.0 tutorial page” and I received the error message below:

404 Not Found

During handling of the above exception, another exception occurred:

Entered all of the required information in the Fitbit application registry.
At the ./auth.sh process, entered correct “Client ID” and “Client Secret” and I get the following after Allowing full access during authentication process:

**Fitbit
The app you’re trying to connect did not provide valid information to Fitbit. Please report this issue to them.

Developer information: invalid_request - Missing parameters: client_id**

Any help would be greatly appreciated!
