[Bug]: the number of vector entities exported is limited

[loic74]

What is the bug? (in English)

Not only is there currently a bug in 3.9 that has caused the layer export button to disappear, but when you choose to export layers from their table or from a script (lizMap.exportVectorLayer), only some of the entities are exported (370 out of 13,500, or 171 out of 17,800, for example). This happens whether you're exporting to shape or XLSX. However, GeoJSON export works perfectly, whether from the script or from the table.
Note that I have no spatial limitations on the export.

Where could the problem be coming from?

I have not installed 3.9.1 or 3.9.2, as no fixes for this issue appear in the changelog.

Thanks ;-)

Hello,
I am experiencing the same issue in a similar context, but with a fresh upgrade to 3.9.2.
The export button has disappeared from the layer information panel and from the attribute table tool (however, it is still present in the selection tool).
With admin user and no restricted export rights.
Thanks for feedback !
