Answer 1

The most common oversight resulting in this error is forgetting to add both HTTP and HTTPS origins on the consent settings in the App Credentials dashboard.

To fix, go to https://console.cloud.google.com/apis/credentials?project=YOUR-APP-ID

Select the OAuth 2.0 client IDs if you had already created one.If not, you will have to create a new client ID for your origin.

Under Authorised JavaScript origins, add both https and http origins for you app if had not added both.
