Cause:
In the ConfigureFiles directory of the controller's ftp, there is no Workspace.xml with the workspace type or mode type set correctly.
Troubleshooting:
Check whether the data in each workspace Info in Workspace.xml under ftp://192.168.39.220/ConfigureFiles/ contains anything unreasonable.
Solution:
Contact after-sales personnel, copy Workspace.xml from the controller's ftp, and send it to after-sales personnel.
Case sharing:
None.
