This error results when Conga Composer cannot access the report and/or the data within the report.
WHAT TO DO
Please check the following items to correct the problem:
- If using a Custom Report Type, ensure it is set to “Deployed” and not “In Development”.
- Ensure the user’s profile has the following permissions: “API Enabled”, “Run Reports” and “Export Reports”.
- Ensure the user has at least Read access to the folder that contains the Report.
- Ensure that the High Assurance Session Required setting is disabled, allowing Conga Composer to access exported report data. If this setting is enabled, the session security level required to export reports is increased, preventing Conga Composer to access the report data.
