What could be a reason for an error shown in the Dashboard component?

A reason for an error shown in the Dashboard component could be that the user does not have access to the report. In many systems, including those that manage dashboards and reports, user permissions are a crucial factor in functionality. If a user lacks the necessary permissions to view or access certain reports that feed into the dashboard, an error will typically be displayed, indicating that the user cannot access the required data.

This highlights the importance of ensuring that all users have the appropriate access rights and roles assigned to them for the reports included in the dashboard. In contrast, other options either suggest scenarios that do not lead to an error or imply that the dashboard is functioning as intended, which would not typically show an error. Thus, access rights are a fundamental aspect of dashboard and report usability.
