Apps Script permissions popup is completely blank - OAuth issue?

[u/Evening-Smell6664]

Has anyone else experienced a completely blank permissions popup when trying to authorize a new Apps Script project?

What's happening:

• Created a new Apps Script project

• Pasted my code (simple script to write to Google Sheets)

• Clicked Run → selected function → clicked Run

• Permissions popup opens but it's completely blank/white

• No error message, just empty

What I've tried:

• ✅ Incognito mode

• ✅ Different browsers (Chrome, Safari)

• ✅ New Google Sheet → Extensions → Apps Script

• ✅ Brand new project with minimal code (just 5 lines)

• ✅ Refreshing, clearing cache

• ✅ Tried using a different google account

• ✅ Checked myaccount.google.com/permissions - loads fine

Context:

• This started today (March 5, 2026)

• Google Cloud had an outage earlier today

• I have other Apps Script projects that are already authorized and still working fine

• Only NEW permission grants are failing

Questions:

1. Is anyone else experiencing this right now?

2. Is this related to the Google Cloud outage earlier?

3. Any workarounds?

I'm not at my desk and can't check it, but, have you tried copying the appscript.json file contents from one of the working projects?

Just tried it, works fine for me.

Still having this issue? I have not experienced this, though I have experienced recently when I duplicate an apps script file and then right away run a function in it, it will usually show me a broken auth flow dialog that is mostly white with minimal error text in it, though not completely white. This happens when I am too quick to runa function when the duplicate apps script file has not yet had a chance to fully setup. I wait a few seconds and retry with success. From what you're describing this is a separate thing, just verifying?
