Unable to download PDFs when they are accessed via library proxy

Relevant error ID: 1979766485

The Zotero Connector (especially to download PDFs) is working when the PDFs are open access (and therefore doesn't seem to be an issue with specific publishers, say), but when it is accessed using a library proxy (that I have included in the proxy settings), it no longer works.

While other threads suspect this is because the URL of the PDF is no longer just a .pdf, and is disguised, because the PDFs of even open access articles have a "disguised URL" but still works with the downloader, I don't suspect that to be the case.

An example of what I mean by a disguised URL : https://watermark.silverchair.com/114102_1_5.0166136.pdf?token=AQECAHi208BE49Ooan9kkhW_Ercy7Dm3ZL_9Cf3qfKAc485ysgAABYkwggWFBgkqhkiG9w0BBwagggV2MIIFcgIBADCCBWsGCSqGSIb3DQEHATAeBglghkgBZQMEAS4wEQQMTSEDPHnybuIR7vkBAgEQgIIFPCPV6Kuz5W8mbnkDjfHkJqAxN5W0LYP5YZUrCkkk8GmITi3jfyMJsQgxs9OvLXYsbdfhL479xecOYh-aTj7UjI2_7OV-QK4b0Dl_BPZW3SCK3OIbq6c9SCkGH9dHEgqykgB-w25imbH24WY5MP7Ys9yuaHDTWHuVqhS9L-edP91xHBICQe7RLvjQisEthfVPdregdIpr6BSX1zsARzpq45ZsYO5MNL2fby07ORnnr69lWuKLNOVGjIu3cso-EtfGLWo6jDCp2b_qv5I7dakzLJdCC58ail2y72OwLOUs5z2PnKaISyZ8loeSGXNwjCJNdfnlJM_uXl-n4_D62Ghxq2gFQr7GPkCZiQOeuEbo9xdaUTIfVcxL9iBcOdb0jj2oB-2bsc-9butBjcdLoTDoDcB6TsiKy8_mrIpIqv32rq2ks-beoCNhcSeSoZkdAt4IPyiO1fFBywjYS8W3N49jOrXH0KrlXo-H_V5fI9YZU8f_i-ulCNKeKWawgSfb1YRQsobQXnz2lrrFy9AMCBwdY8i7usM-3b5cLWZ9UjGviyMOWLxMB6X4Bult3W4XrDk4ZV_iaV0SDJIE7VcvZqj0kSHNxki6uvFohhv78w_eZMPqOTLrEmw0u89Kc5sXOc0pJMDguf21dXP8_feYapyia_PUGvamOaMKqKv3lF-t3vRMXptqTLDXU80H5WKqvwjp9q4CQhAPfSBN0R5Kd8nBGUFyU0dkvWhEJ6hqp4vXxkCo5v-gnP24Epd2VC5huXmBgC8Otx4-ItbIPrhKV35Es5qhIhU33DwLqSG3oqDsbiOy47y8cmdemyj1M0pWvIFxNhMDuQzVyRH2v9UivaQHrKcs1bqENsTdM6L52AO3ki3AHO7Bja67sMfFm1KxH204bHIMGterwIYf6E2InL9DnRsyEn_Zo_n_z9QSPYX0nm7_Dj1YmmYJE6_koWOt8JK-KXRB3RsnXZjgzChhS4YErGgBqd9qxVuioeYXwFS-ZNg1Jw1cnVFYMghsPMl4vqu4N63MrxpgMk-O-5FR5KyiRgT20onjPayP0JvId89JeC1zaCSw1gWHNeq2tjwf1HLCkcC6Z5CjbLASnuweOoYw2OT6gTQ5xyI_5PUsczVQL-azQgEMK5W49Hdc-2Ok0MOUMCdSyTgCaJxYeQkdiJK_rqyX_zTL-QgcICWLaemefWNXnWol09j_yqDtTYYwAyslR71apwbZA_ifvvxTm7nHU7dlXtAUNk32tLUVSAU7tPXf_kNftH0T6ptg3rApBlRuQQYSyFUyfggTjoRI1vXYOn30ebMprV0hXevRWqMij9Ki6bNYdrQVzbaT1wpF8OpdCg59nb8AaG17uen1N2OoVQyLVbyQXr6Pse51A6QsGgDGzc-DYe2JDU8C2bF3lnyu0A53i5FC63wXpYM0MFLJGCl5yzLUhSfcTdpe0DPcRVW-6j8B4oO2dUuSdtr6FEMj1PQctslbt9pjySD4fZibMU_fvjpo4m5rJeq9MHBmQKBZI08BkiORZHNkOja-AQb9koWnncDaZrvjHBxJt_ox5iaZRvx2ed7KnxvG9KSNzqXyrCxfWwuz-wHfh1MwYnpdTqKztCtNw9ek3qidaghcyH9dNXoVzqYmeySc_Y14mas4jcUKKmGaBagz3pJTZ6_vp0kLBPsCDR-Mi7rcztm3GtFZV6Wf_RTFU7Yv6luJdr7tOpKtprZDeJVUKU1QSNY9wO-EqDr8cEHf9rCxgYwYJBjv2L4Bl5Yya2OILtZ9_ntUVK0gwQL70V3Sx618

Perhaps for further reference, I also use the LeanLibrary extension in order to access the PDF.

I *really* don't want to have to do it the long way round : i.e. download the PDF and add it to the relevant item manually.
  • Are you trying to save a PDF directly or save from the article page? Generally you want to do the latter, and Zotero will download and attach the PDF if you have access to it.

    In any case, for a download problem we'd want to see a Debug ID from Zotero (rather than a Report ID from the Zotero Connector) for reloading the URL and trying to save.
  • Thanks for your reply.

    I forgot to mention this, but if I try to save from the Article Page, it saves the snapshot (and other metadata) but it fails to download the PDF.

    I tried downloading a different article, and saved the output. This is the debug ID : D2128639500

    I hope this helps.
  • That's a Debug ID from the Zotero Connector, not from Zotero, but also, that's ScienceDirect, not Silverchair. For ScienceDirect, see https://forums.zotero.org/discussion/comment/451390/#Comment_451390
