Adobe Salesforce Connector - INVALID_SESSION_ID

Issue:

I have integrated AEM with Salesforce using salesforce cloud config. I am able to connect to salesforce successfully and able to pull data from salesforce. After sometime when I access aem page am getting error below

[{"message":"Session expired or invalid","errorCode":"INVALID_SESSION_ID"}]  

I have also checked below settings in salesforce

• Session timeout after 4 hours of inactivity
• Selecte OAuth scopes
•  Perform requests on your behalf at any time (refresh_token, offline_access)
• Access and manage your data (api)
• Full Access (Full)

Resolution:

In sales force we need to remove Full Access (Full) OAuth Scopes, if we use this then refresh token will not be effective.
