Unable to Upload a Change Set That Contains Reports and Dashboards in Salesforce

This article explains how to resolve an Internal Server Error when uploading a Change Set that contains reports or dashboards. The error occurs because one or more report or dashboard components are inaccessible — either deleted or stored in a personal folder.

Review the List of Report and Dashboard Components in the Change Set

To resolve this issue, verify whether you can access all report and dashboard components included in the Change Set.
If the report has been moved to a personal folder by another user, you will see the following error:

Insufficient Privileges You do not have the level of access necessary to perform the operation you requested. Please contact the owner of the record or your administrator if access is necessary.

To identify which user moved the report, refer to the article Locate Reports and Dashboards Stored within Personal or Private Folders in the Additional Resources section below. That article explains how to run a query to determine who has moved the report to a private folder.
If you have access to all of the reports, check the Properties of each report to confirm you have not personally saved any reports to a personal folder.
Once you have identified the inaccessible reports or dashboards, take one of the following actions:

• Reach out to the owner of the report and request they move it to a shared folder.
• Remove the inaccessible report or dashboard from the Change Set and re-upload without it.
