JavaScript errors in ru:Vlsergey/wef.js

[jdlrobson]

Apologies if this is the wrong place. I posted this on the talk page but got no response so trying here. The script at https://ru.wikipedia.org/wiki/%D0%9E%D0%B1%D1%81%D1%83%D0%B6%D0%B4%D0%B5%D0%BD%D0%B8%D0%B5_%D1%83%D1%87%D0%B0%D1%81%D1%82%D0%BD%D0%B8%D0%BA%D0%B0:Vlsergey/wef.js is generating a high volume of errors consisently.

I am seeing quite a few errors in our error logs relating to this error namely:

Error: Unknown entity type: на смену! Uncaught TypeError: Cannot read property 'cloneNode' of undefined TypeError: e is undefined

Because the script is minified I am not getting useful stack traces. I hope with this information you can track down these errors and help fix them.

Side note: Would you consider modifying Участник:Vlsergey/wef.js to be unminified and pointing to its source code on wiki. It was hard to find this.

@jdlrobson , what page (URL) error is generated at?

Let me know if you need more examples, and thanks for looking into this!!

@jdlrobson , sadly i'm unable to repeat specified problems on any of those URLs. I will describe a bit later how to "debug" WEF code on local machine (without uploading 10 Mb source file to wikipedia)

I can replicate the TypeError: e is undefined at this URL: https://ru.wikipedia.org/w/index.php?title=%D0%9A%D1%80%D1%83%D0%B7%D0%B5%D0%BD%D1%88%D1%82%D0%B5%D1%80%D0%BD,%D0%98%D0%B2%D0%B0%D0%BD%D0%A4%D1%91%D0%B4%D0%BE%D1%80%D0%BE%D0%B2%D0%B8%D1%87&action=edit&useskin=minerva

Hope that helps get to the bottom of this...
