Upgrade StorageZotero 10.0.2 Find Full Text queue stops after an HTTP 502 error
Hello,
I am experiencing a reproducible problem with the Find Full Text function in Zotero 10.0.2 on Windows 10.
Environment
Zotero version: 10.0.2 (64-bit)
Operating system: Windows 10 (19045)
Locale: zh-CN
Zotero was tested in Troubleshooting/Safe Mode with all extensions disabled
extensions.zotero.findPDFs.resolvers is set to []
The Zotero library contains approximately 17,000 items.
Problem
When I select a batch of approximately 20–22 items and use Find Full Text, Zotero can successfully find the PDF for the first item, but then the process stops progressing on a subsequent item.
For example:
Select 22 items.
Right-click → Find Full Text.
The first item is processed successfully.
After that, no further items are processed for more than 10 minutes.
Restarting Zotero and repeating the exact same operation produces the same behavior: the first item succeeds, and the queue then stops progressing.
This makes large-batch Find Full Text operations impractical. I would like Zotero to skip a failed PDF request after a reasonable timeout and continue processing the remaining items.
Debug output
Debug ID:
D191531454
The debug output contains repeated errors such as:
Request timed out after 30000 ms
and repeated HTTP 502 errors from IEEE Xplore:
HTTP GET https://ieeexplore.ieee.org/stampPDF/getPDF.jsp?... failed with status code 502
The same IEEE request appears repeatedly in the debug output.
Additional observations
I previously had custom PDF resolvers configured, including several Sci-Hub resolvers. After removing them and setting:
extensions.zotero.findPDFs.resolvers = []
the performance of single-item Find Full Text improved substantially.
However, the batch-processing problem described above still occurs.
I have also tested the following:
Manual PDF downloads in a web browser are fast.
Dragging a manually downloaded PDF into Zotero works immediately.
Zotero's WebDAV server verification succeeds.
Disabling automatic sync does not resolve the Find Full Text problem.
Changing the proxy setting temporarily did not resolve the problem.
The problem persists with Zotero extensions disabled.
Expected behavior
If a PDF request fails or repeatedly returns an HTTP 502/timeout, I would expect Zotero to mark that item as unsuccessful and continue processing the remaining items in the Find Full Text queue.
Actual behavior
A failed request appears to keep the Find Full Text process from progressing to subsequent items for an extended period of time. In a batch of 22 items, the first item succeeds but subsequent processing can remain stalled for more than 10 minutes.
Could you please advise whether this is expected behavior, or whether there is a setting or fix that would allow failed PDF requests to be skipped so that the Find Full Text queue can continue?
Thank you for your help.
