PageImages returned 0-height image for page {title}, {fileName}

Impact

Unclear.

Notes

This is happening almost exclusively at wikidatawiki, where GrowthExperiments was recently enabled. See T418115: Configure newcomer dashboard for Wikidata (per community consensus). However, I can also see few entires for zhwiki.

Usually, this is associated with PDF files as filenames.

From a 1:1 between @Michael and I, we should probably detect if the image is a PDF and if so, not return any thumbnail image.

Just chiming in to say that I also observed this error when doing chores today. There were 2,742 occurrences in the last 24 hours.

We can consider working on this to silence the logs. Feels straightforward from what @Urbanecm_WMF has shared.

DMburugu moved this task from Inbox to Needs Refinement on the Growth-Team board.Jun 25 2026, 4:42 PM

Looking through the amended logs, it seems that $imageFile->getMimeType() is always 'application/pdf', and $imageFile->getMediaType() is always 'OFFICE'(!?).

I suggest we use $imageFile->getMimeType() when tackling this task.

There was a task about `img_media_type='OFFICE' triggering a production error T332757: Invalid file error for Add image - OFFICE is not valid mime type . There was also some discussion - starting https://phabricator.wikimedia.org/T332757#8725862.

The impact of this production error is unclear (as it's stated in in the task description). The level is WARNING, the volume is large - 2,156 reports in 24 hours - https://logstash.wikimedia.org/goto/bfdc418f5c9fdcd14fb40c2371546174.
The significant increase in the nuber of the reports started on 2026-06-16 - https://logstash.wikimedia.org/goto/8b9544bef7afeb2f2e912fec7fa71571.

I checked PageImages returned 0-height image for page Q140298320, Il_Liceale_n.2_(2025-2026).pdf. The image is not included in any of wikipedia pages - checked https://www.wikidata.org/wiki/Q140298320 and https://commons.wikimedia.org/wiki/File:Il_Liceale_n.2_(2025-2026).pdf.
