Troubleshooting Common Issues
Here are some typical problems and how to resolve them:
Placeholders Not Merging Correctly
• Double-check placeholder names **exactly match** your form question titles.
• Avoid extra spaces or punctuation in the placeholder (e.g., {{Full Name}}
is valid, {{ Full Name }}
is not).
• Verify that placeholders exist in the template.
Certificates Not Generating
• Ensure a destination folder is selected.
• Check that a template is selected and placeholders are mapped.
• Review the execution logs (in Apps Script Dashboard) for specific errors.
Permissions Errors
• Ensure you’ve granted access to Google Drive, Forms, and Slides.
• If the add-on prompts for permissions again, reauthorize from the add-on menu.
Images Not Appearing in Certificate
• File upload fields must be mapped correctly as image placeholders (e.g., {{Photo}}
).
• Uploaded files must be shared with anyone who has the link for access.
• Avoid non-image file types.
QR Codes Not Scanning
• Check that the QR code size in the template is large enough (minimum 100x100px recommended).
• Verify that the QR placeholder is correctly merged using the {{QR}}
tag.
• Test the QR output with a mobile device scanner.
