Self-hosted instance always returns error "An unexpected error has ocurred. Please try again later."

[thomasfischer-his]

I have setup a self-hosted instance of AMP. The webpage for providing an URL, HTML code, or uploading a HTML file appears in my browser when visiting http://localhost:4200 and looks like https://accessmonitor.acessibilidade.gov.pt/. However any attempt to validate an URL, HTML code, or an uploaded HTML file immediately shows the following error message:

 An unexpected error has ocurred. Please try again later. If the problem persists, please contact us.

Submitting the same URL or HTML code to the 'official' instance (https://accessmonitor.acessibilidade.gov.pt/) works without problems.

On the container's console, the most recent output is:

✔ Browser application bundle generation complete.

** Angular Live Development Server is listening on localhost:4200, open your browser on http://localhost:4200/ **


✔ Compiled successfully.

So, no error output. I couldn't find any log files in the container's filesystem, but it is possible that I looked at the wrong place.

Is it possible to run AMP in some debug/verbose mode to collect more information?

I am using the following Dockerfile:

FROM andrewmackrodt/nodejs-chromium

EXPOSE 4200 4200

ENV SUDO_NOPASSWD 1

USER root
WORKDIR /usr/app

RUN echo '> > > apt-get update -qq' && apt-get update -qq && echo '> > > apt-get install -qqy --no-install-recommends vim less netcat telnet iproute2 git bash' && apt-get install -qqy --no-install-recommends vim less netcat telnet iproute2 git bash && echo '> > > rm -rf /var/lib/apt/lists/*' && rm -rf /var/lib/apt/lists/* && echo '> > > git clone --depth 1 --single-branch https://github.com/amagovpt/access-monitor-plus.git' && git clone --depth 1 --single-branch https://github.com/amagovpt/access-monitor-plus.git

CMD ["./node_modules/.bin/ng", "serve"]

Instead of Docker, I am using Podman 4.2.1. The container's network is set to be the host's one (--net=host).

Hi, it looks like you have deployed AMP correctly but it seems like you are not running our back-end application https://github.com/amagovpt/monitor-server.

[thomasfischer-his]

Thanks for the reply. I was loking into amagovpt/monitor-server, but it seems to have an issue of itself.

@thomasfischer-his Did you have success with your installation and make a docker container to run AccessMonitor+monitor-server locally? If yes, is it possible to share the Dockerfile?
