Odoo using Traefik proxy instead of Nginx

I have successfully used Traefik for several containerized applications and I am happy with the native SSL support using LetsEncrypt (Thank you very much Traefik team). However, specifically, to run Odoo (Open-source ERP/CRM), I am getting an exception in the back-end and also in the browser via javascript logs: Exception: bus.Bus unavailable + the call stack not important here. Apparently, the root cause of this exception is that Traefik is not proxying the requests coming to the URL /longpolling when the parameter workers > 1 in the odoo.conf file.

The Odoo server exposes two different ports:

I made a GitHub Repository explaining how to reproduce this "bug" (I don't know if it's a bug or if I don't know how to use it properly).

As a reference, I also added one nginx.conf file not using SSL (just to make it simple).

Here is my docker-compose.yml used to run Odoo + Traefik:

      - traefik.http.services.odoo-https.loadbalancer.server.port=8069

       #====> On the next line was my mistake. It was typo as pointed out by @Veikko
      - traefik.http.routers.odoo-im-https.rule=Host(`${ODOO_HOSTNAME}`) && (PathPrefix(`/longpooling`))
      - traefik.http.routers.odoo-im-https.entrypoints=https
      - traefik.http.routers.odoo-im-https.service=odoo-im-https
      - traefik.http.routers.odoo-im-https.tls.certresolver=le
      - traefik.http.routers.odoo-im-https.middlewares=gzip,sslheader
      - traefik.http.services.odoo-im-https.loadbalancer.server.port=8072

      # middlewares
      - traefik.http.middlewares.gzip.compress=true
      - traefik.http.middlewares.sslheader.headers.customrequestheaders.X-Forwarded-Proto=https

The closest solution that I found was on this question on the Traefik forum, suggesting to include the line below (which I tried, but still did not work): traefik.http.middlewares.sslheader.headers.customrequestheaders.X-Forwarded-Proto = https

I may have missed something, but I could not figure it out.

Thoughts?

Correct Odoo url path is /longpolling. Check that your Traefik and Odoo configurations use longpolling, not longpooling, e.g. the Odoo container labels for Traefik ...PathPrefix('/longpooling')" -> ...PathPrefix('/longpolling')".
