How to ignore Sci-hub Plugin error: "Captcha is required" in Zotero 6

zara.rashid · February 23, 2024

I would like to retrieve PDF of articles using Sci-hub Plugin for Zotero 6. After selecting multiple articles and choosing "Update Scihub PDF", Zotero downloads some articles but for the articles it does not find, it shows an error "Captcha is required" and stops there. Obviously, the error is because the article is not available in Sci-hub.

However, I want Sci-Hub plugin to ignore the error "Captcha is required" and continue downloading the articles which are available. How can I do this? Is there a javascript code for this?

For problems with a plugin, you'll need to contact the plugin developer.

There is also a sci-hub script for the zotero-actions-tags plugin (which also works with the Zotero 7 beta; the original zotero-scihub plugin does not yet do so) ...

@dstillman and @tim820
Thanks for the answers. The problem still persists. I'll find an alternative plugin.

Sci-hub is currently experiencing issues in many countries for the official links. Mostly returning a blank screen. But that is a different issue to the captcha.
