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.
