I'm trying to create an event in Google Calendar using the Ballerina Google Calendar Connector. I'm using the OAuth 2.0 Playground to test the code. I used https://oauth2.googleapis.com/token as the refreshUrl, but I received the following error:
"error: Failed to call the token endpoint 'https://oauth2.googleapis.com/token'"
I provided correct clientID, clientSecret, and refresh Token, and followed the steps in the documentation
How can I fix this?
