Zotero Edge Connector cause js errors in my website

nixiak_nan · August 18, 2023

From 4am on August 18, 2023, Beijing time, some users reported that they could not click the "注册(register)" and "登录(login)" buttons on my website, and the routing of vue was invalid. Closing the zotero connector resolves the problem.

My environment:
edge 115.0.1901.203 (64-bit)
Zotero Connector 5.0.112
https://www.easyscholar.cc

Repeat steps:

1. Visit https://www.easyscholar.cc, click "登录(login)" button in the top right corner, have correct dialog window.
2. Install zotero connector, refresh the web page, wait for a few seconds, and click the 登录(login) button again. Unable to pop-up dialog window. A TypeError: Cannot read properties of null (reading 'insertBefore') is displayed in F12 console.
3. Close the zotero connector, refresh the web page, and click the "登录(login)" button in the upper right corner. A correct dialog window is displayed.

In addition, the routing error message is:
TypeError: Cannot read properties of null (reading 'nextSibling')
TypeError: Cannot read properties of null (reading 'parentNode')

@nixiak_nan: Did you update Vue or some other library? We haven't updated the Zotero Connector in weeks, so either there was a browser change or there's some conflict with a third-party library. And we got one report from Firefox, which would suggest this is a conflict with a library.

I don't think it's because I haven't updated the front-end code in the last week. As for the browser changes you mentioned, I am looking for an old version of edge browser to test.

Did you make any kind of site changes before this happened? This is happening in both Chrome and Firefox, so it can’t really be a browser change, and we haven’t updated the Connector.

I found another site that can reproduce this scenario, and I'm using their third-party library. However, I am not sure if zotero connector only conflicts with this third-party library. And I haven't updated the version of the library or introduced it dynamically, so the code should always be the same.

1. Access the website and press ctrl+f5 to refresh
2. click to open the dialog. The window cannot be displayed
3. Close the zotero connector and refresh the interface
