Custom OAuth2 Social Connection with Cognito Returns Error "Invalid user id"

When setting up a Custom Open Authorization 2 (OAuth2) Social connection with Cognito, the user is redirected to an error page during login attempts.

The error message displays the following: "Invalid user id"
 

• Custom OAuth2 Social connection

• Cognito

This error occurs because a fetch user profile script is not implemented for the connection:

function(accessToken, ctx, cb) {
    const profile = {};
    // Call OAuth2 API with the accessToken and create the profile
    cb(null, profile);
  }

• Configure the fetch user profile script to resolve the issue.

• Refer to Fetch user profile script for configuration details.
