IOException: Failed to start kernel, caused by: SecurityException

This issue occurs when the user doesn't have credentials set for sharepoint-online plugin.
As mentioned in the documentation each user must manage their own credentials individually in their DSS profile.
Users can enter their personal credentials by performing the following steps:
1. Navigate to DSS profile page by clicking on profile icon in the top-right of the UI.
2. Click on username > go to the “Credentials” tab > "Plugin credentials".
3. Click on the edit button for the sharepoint-online plugin preset. This will redirect to a Microsoft single sign on page.
4. Log in to the account (if prompted) and click on "Yes".
