*you can get a list of all attachment file paths with Zutilo, or a list of all stored or linked files with javascript.

Everything fine here in the meantime, no more assistance needed at this point. The problem was possibly resolved by a JavaScript update this morning.

First, the JavaScript solution (shared by @marcelparciak in 2020) does not work anymore, unless you use older version / has not update zotero since 2020. It will throw errors like “ReferenceError: Zot

[JavaScript Error: "uncaught exception: undefined"]

output to stderr (i.e. `console.error('...')` in JavaScript, `print('...', file=sys.stderr)` in python) and it will appear in this log. { metadata: undefined }

[JavaScript Error: "Error: Failed to load resource://services-settings/remote-settings.sys.mjs"]

To get an exact number, you could paste this line in Tools > Developer > Run Javascript, and press Run:

[JavaScript Error: "Request timed out after 30000 ms"]

At one point I had a very long javascript error pop up, but that has only happened once. This issue happens in chrome and edge, and in both personal and private windows. I can't even select to change

[JavaScript Error: "URL constructor: undefined is not a valid URL.

Revert any changes you made to the sqlite directly (i.e., restore from a previous backup). That's a recipe for disaster all around and Zotero has various scripting options (API, local JavaScript API),

We'll fix the startup hang, but for now, you can go to Tools → Developer → Run JavaScript and run this to fix your database:
