"ACM Digital Library" translator broken with proxy

lucj

I have a proxy set up under the form https://%h.recursos.biblioteca.upc.edu/%p with hyphens translation in the hostname. Thus for https://dl.acm.org/ we get https://dl-acm-org.recursos.biblioteca.upc.edu/ but saving to Zotero fails. This works fine for other translators, e.g. with Springer Link we get https://link-springer-com.recursos.biblioteca.upc.edu/ and I have no trouble saving the reference.

It seems the proxy is applied twice when the translator fetches the bibtex export from the page, the detail is uploaded in report id D790223056, but there are some excerpts below. The url it tries to fetch is: https://dl-acm-org-recursos-biblioteca-upc-edu.recursos.biblioteca.upc.edu/downformats.cfm?id=2485927&parent_id=2485922&expformat=bibtex

As a workaround I can save using this translator when disabling the proxy, but then I need to add the file manually since I only have access to it through the proxy.

Thanks -- I think I know what's going on, but not sure how easy/hard this is going to be to fix, so might take a little:

Technical note for anyone else interested in looking at a fix: the problem is that we're not using the url the bibtex is generated from from the translator in scrape, but instead grab it from the page, where it already appears proxified (and the re-proxify it). See https://github.com/zotero/translators/blob/master/ACM Digital Library.js#L83

This should be fixed now. Thanks for reporting

Just updated translators, and it works fine now indeed.
Thanks!

Still doesn't work.

The original error here was fixed. We'd need more details following https://www.zotero.org/support/troubleshooting_translator_issues

I think it has to do with my proxy. If I use ACM at my University network, zotero connector works fine. But now I'm at home and using the University proxy and it doesn't work.

We'd need to see exact URLs still as well as a description of what's happening.
