Docker compose exporter failing on export

Self-host
1

Hello, there Penpot Community!

I’m reaching to you as I’ve run into a problem (of course) and cannot fix it, which has been flustering me for some time now.

The problem happens no matter if I want to export frames, single assets or components in any kind of format. The issue just happens every single time with similar kind of log.

The user and file permissions are properly set up, I’m not using the user with penpot-frontend because it fails for some reason if I do that, but backend runs smoothly. I’ve tried running penpot-exporter as root which didn’t bare any fruits.

Another thing to take note on is that I’m using Nginx Proxy Manager as my reverse proxy, which in itself shouldn’t be of issue. I did use Cloudflare as an proxy (orange cloud) but also tried to without it, which in both cases led to the former again.

Anyways, most importantly, here is my docker-compose.yml:

Besides that, here is the issue I’ve been having:

Log provided by the frontend via the download report button:

Thanks for your time.

Sorry had to remove my comment, as my issue was related to coolify auto generated url to one of my preassigned environment variables.

It is still an issue for me as of 06/10/2025.

I had this issue but i have entered the exporter image with root user and ran the following commands

apt-get update

apt-get install imagemagick

npm install imagemagick

now i can export webp, and any combination of file format correctly
