2. Upload the prepared .xlsx file.
3. Observe the error "File upload failed."
4. Select View details and see "An error occurred in the upload. Contact the system administrator."

5. Upload the corrected .xlsx file again.
6. Optional workaround if the file is generated by an external system: open the file in Excel and Save As an Excel Workbook (.xlsx), then upload the saved file.
