[GeoNetwork-users] thumbnails generation in 3.10.10

Hi all,

I had a GN version 3.10.5.0 that was able to generate thumbnails from a WMS service.
I updated GN at the version 3.10.10.0 and it seems it is not able to create thumbs from WMS anymore.
I checked with chrome devtools and if I inspect the map within 'link to an oline resources' - add a thumbnails,
I got 'Failed to load resource: the server responded with a status of 400() and a list of
[Violation] 'setTimeout' handler took 76ms.

Do you know anything about this issue?
