What happened?

After install using apt install crowdsec-nginx-bouncer nginx will not start due to error:

What did you expect to happen?

Nginx to start successfully and the bouncer to function.

How can we reproduce it (as minimally and precisely as possible)?

apt install crowdsec-nginx-bouncer on Debian 12

Anything else we need to know?

Hello,

The issue is because we do not specify a specific version for our lua dependencies, and it looks like lua-resty-http got updated 2 days ago, and now requires lua-resty-string.

I've opened a PR to use the previous version while we check how to update to the latest version.

In the meantime, you should be able to fix your installation by running luarocks install lua-resty-http 0.17.1-0 and restarting nginx.
