Failing to load extensions on Linux

[bazmattaz]

Hi there. I want to setup Zendriver with proxies. I created a folder called extensions where I store a manifest.json and background.js which contain information of the proxy server I want to use. I then pass the following browser argument in the main script when starting the browser;

f"--load-extension={extension_path}"

This works locally on my Mac and uses the proxies perfectly but when deployed in Docker on Ubuntu Server 22.04 I keep getting this vague error. Passing no_sandbox=True doesn't do anything.

app-1  |                 ---------------------
app-1  |                 Failed to connect to browser
app-1  |                 ---------------------
app-1  |                 One of the causes could be when you are running as root.
app-1  |                 In that case you need to pass no_sandbox=True

My script works fine without the browser argument, it's then I can use proxies.

Do you have any idea how to fix or debug this? Thanks in advance 🙏🏻

Hey @bazmattaz, are you copying the extensions from extension_path to the Docker container during build?

By default, everything from the project directory is copied to the container under /app (see here). So, for example, the pyproject.toml file in the repo would be at /app/pyproject.toml in the container.

If your extensions are not stored in the project directory though, you will need to modify your Dockerfile to copy them to the container.

nah it's still the same shit as on all the repos, and also the initial uc repo, same shit, I just did the tutorial and this is the exact same error that pops out, you didn't solve the issue at all

the error goes away with the same setting, with sandbox false and headless true, like you didn't do jack shit
