The API developer key is invalid.

Hi
I followed the video’s instructions here:

https://awsm.in/drivr-documentation/#cloudapi

Created new project, generated the ID and key, saved the settings.

In the Edit Post page, when I click the Add From Drive button the first time, I get the Google permissions popup asking if it’s ok to give Drivr Lite access, which I do. But then the popup shows:

There was an error!
The API developer key is invalid.

There’s no way to get rid of this box except to close the tab.

If I check the Google APIs dashboard for the project, it says there was one request for the Google Picker API and one error. When I click through to the API usage report, it says “Client errors (4xx): 0” however that’s the only kind of error listed.

Little help?
