Thanks for reporting. We will have a fix out soon that will make the lock override work. Do you have any idea how the document got to this state in the first place? Do you have many citations in the document? Did you get any errors from the integration before you started seeing this?

The fix is now out with the Connector version 5.0.49. Make sure you refresh the google docs page after updating.

PS: The update also seems to render Zotero fields in Google Docs in a grey color which is super useful!

Hello guys,

Im having a similar problems. Im using zotero 5.0.55 with google chrome 69.0.3497.100 64 bits and zotero conector 5.0.49 on windows 10 on a portable pc.

I started using the beta zotero version to try out the google docs integration with firefox a few months a go in a document from scratch. As it didnt came up with any issues, I started using it with chrome as it came with the stable version. Although I dont believe this is an issue, at work I use a pc with different stuff, windows 7, the Chrome takes longer gaps to update.

I have no more the 100 citations. I have collaborators for this document but none of them use zotero and neither they are familiar with bibliography management. Im not using automatic update.

It was working fine up to a week or two a go then the following error is coming when I press refresh:

"The document citations are being edited by another Zotero user. Please try again later."

When I press "Help"...

"Zotero locks your document to prevent multiple users from editing citations at the same time. Concurrent citation editing in the document may lead to citation or document corruption. Certain unforeseeable circumstances, such as network failures, may lead to your document becoming permanently locked. If you believe this has happened, you can override the lock."

Then I press "unlock"

"Zotero found the following error when updating your document.

Too many changes applied before saving document. Please save changes in smaller batches using Document.saveAndClose(), then reopen the document with Document.openById()."

Have no idea what it means. But Im convinced that none else is editing the document when I try to refresh.

Any tip in what should I do?

Would you be willing to share a copy of the document with Zotero developers for debugging purposes? If so, could you make a copy and email an editable link of the document to support@zotero.org?

We've had one other report of this problem, but we cannot reproduce it ourselves and are not sure what is causing it. If you cannot share a copy of this document with us, you should make a copy of the document and try 2 things:

1. Remove chunks of the document from the end of it and see whether the integration starts working again.
2. Go into the document version history (File -> Version History) and try to find the last version of the document that worked. Then copy the changed contents of the document from your copy and see whether the integration will get stuck again. Note that if you do this, Zotero citations that you copy from the document in the broken state, which do not existing in the older working revision will not work and be treated as simple text by Zotero and will need to be reinserted.

+1 from me. When try to unlink, I get "The document citations are being edited by another Zotero user. Please try again later". When I try to override, I get the blue progress bar for a couple of minutes and then the "too many changes applied" error.

Im not sure if you are testing in the same document that I can see or a copy of it that I can't see. Looking at the document that I shared and I can see, I can't find what exactly what you changed. If you just inserted a new citation then I must say that I could do that too in first place. For me, the issue remains. When I press "refresh" at the zotero's menu the erros described above pop up. When I try to insert a new bibliography, the edit bibliography window pops up, I click "ok", then after a while the error comes:

"Too many changes applied before saving document. Please save changes in smaller batches using Document.saveAndClose(), then reopen the document with Document.openById()."

@pedrobrasil We have published the fix for the Zotero Connector beta for Firefox. You will be prompted to authenticate Zotero with your Google Account and might get a scary screen saying the app is unverified. We are in the process of verifying the Beta version of the Google docs addon with Google, so you should click "Advanced" in the bottom of that screen and click "Go to zotero.org (unsafe)", then finish the authentication procedure normally.

Also note that the first refresh of your document is likely to be very slow (up to 1hr), but with the fix subsequent updates of the document will be much faster (a couple of minutes).

The prompt allows you to override the lock as well as specify that it can become locked by accident. Do you still get the problem if you override the lock? If not you should not worry about it.

Depending on the size of the document the update might take a while. If it works fine in a new document you should give Zotero time to work.
