That's great news, thank you Andrea. I checked Jira before sending the
message, but couldn't find anything. I think I was just searching for
open issues.
Anyway, for future reference, the ticket number is GEOS-10547 [1]

Hello,
A while a go we reported that we were having trouble to cache
vnd.mapbox-vector-tile tiles in Geoserver[1], but we were not able
to provide the steps to reproduce the bug. After some more
digging, we finally found what causes the trouble.
Enabling the 'WMS integration' and disabling the 'explicit tiled
parameter' causes a back and forth infinite loop between Geoserver
and GWC when trying to obtain vector tiles. According to our
tests, this is what happens:
* GeoWebCache asks Geoserver for the missing tile when it's not
already cached.
* Geoserver, instead of generating the tile, asks GeoWebCache if
the tile is cached.
* GeoWebCache again asks Geoserver for the tile.
* ... infinite loop between the two services until the
stacktrace is so big it causes a StackOverflow
The bug can easily be reproduced by using Geoserver's official
Docker image:
1. Run Geoserver: 'docker run -it --rm -e INSTALL_EXTENSIONS=true
-e STABLE_EXTENSIONS=vectortiles -p 8080:8080
docker.osgeo.org/geoserver:2.21.1
<http://docker.osgeo.org/geoserver:2.21.1>'
2. Login to admin panel. Default credentials admin:geoserver
3. Enable 'application/vnd.mapbox-vector-tile' Tile caching for
layer tiger:tiger_roads (we are taking this as an example, but
any should cause the same)
4. Request tile to TMS:
'curl -u admin:geoserver
http://localhost:8080/geoserver/gwc/service/tms/1.0.0/tiger:tiger_roads@EPSG:4326@pbf/12/2412/2975.pbf'
The request will succeed and will return a binary output (we
don't really care about the content). So we confirm that by
default the tile generation/caching works.
5. Disable 'Explicitly require TILED Parameter' and enable
'Enable direct integration with GeoServer WMS' under Tile
Caching / Caching Defaults
6. Clear cache for layer 'tiger:tiger_roads'. Tile layers /
'tiger:tiger_roads' / 'Empty'
7. Enable the VERBOSE_LOGGING profile
8. Ask for the same tile again
'curl -u admin:geoserver
http://localhost:8080/geoserver/gwc/service/tms/1.0.0/tiger:tiger_roads@EPSG:4326@pbf/12/2412/2975.pbf'
The request will return a 'GWC Error': '400: Problem
communicating with GeoServer' and while generate a huge
stacktrace. Depending on the PC the request may take a while.
The single tile request generates a log file of 418815lines and
34Mb. As it's too big to send it here I uploaded it to GDrive:
