rsyslog + nginx live log import silently fail

It probably have some comon point with #258

I've followed the rsyslog part of this : https://github.com/matomo-org/matomo-log-analytics#how-do-i-setup-nginx-to-directly-import-to-matomo-via-syslog

and after some folder manual creation and the change of /var/cache/nginx/access.socket by /dev/log in nginx.conf and 10-matomo.conf if i uncomment the debug line local0.* /var/tmp/nginx.tmp;matomo, log apear in /var/tmp/nginx.tmp

If i try to import them with matomo.sh it show me the script run, but import nothing.

If i try to run import_logs.py itself, it work.

So i suspect there is something not working in /usr/local/matomo/matomo.sh

 cat /var/tmp/nginx.tmp | ./misc/log-analytics/import_logs.py --url=***** --token-auth=******  --enable-http-errors --enable-http-redirects --enable-static --enable-bots --recorders=4 --log-format-name=nginx_json -

found nothing to import but :

./misc/log-analytics/import_logs.py --url=***** --token-auth=******  --enable-http-errors --enable-http-redirects --enable-static --enable-bots --recorders=4 --log-format-name=nginx_json /var/tmp/nginx.tmp

work

Is there some documentation to fix in README.md about rsyslog /usr/local/matomo/matomo.sh syntax :

echo "${@}" | /***MY_MATOMO_FOLDER***/misc/log-analytics/import_logs.py

or is it something to fix in misc/log-analytics/import_logs.py ?

or anything else i've not spotted ?

After reading this : https://github.com/matomo-org/matomo-log-analytics/issues/282#issuecomment-716676600 i've updated import_logs.py to the latest from this repository. I've change in first line : #!/usr/bin/python to #!/usr/bin/python3 and it now have the same behavor with this 2 way for calling it :

cat /var/tmp/nginx.tmp | ./misc/log-analytics/import_logs.py [...] -
./misc/log-analytics/import_logs.py [...] /var/tmp/nginx.tmp

But it does'nt import anything :
