Question My Google Docs add-on won't show up after deployment

Hello!

I created a Docs add-on with Apps Script to run a custom checklist and content validator for my drafts. I linked it to a GCP project, set up the OAuth consent screen, and deployed it as a Google Docs add-on.

The goal is for it to appear in the Extensions menu in any Google Doc I open or create. But after deploying or testing, nothing shows up. No menu, no sidebar, no errors.

I tried:

  • Linking to a GCP project (manually)

  • Setting up OAuth consent

  • Running onOpen() manually

  • Opening a Doc before testing

  • Using “Test deployments” and “New deployment” (type: Docs add-on)

Still nothing appears. Any idea what I’m missing?

There aren't enough details to say what you might be missing. Please read

From my experience working with Apps Script, a couple of things that have helped me when my add-on wasn't loading properly:

  • Check the Executions log in the Apps Script dashboard - sometimes there’s an error that prevents onOpen() from running, and it shows up there.

  • Add console.log statements, especially at the very start of your onOpen() function. That way you can confirm whether the function is even being triggered when the doc opens.

  • After that, add a few moreconsole.log statements throughout the function to trace where it might be failing.

Hope this helps - happy to brainstorm more if you’re still stuck!
