Hey all, I'm getting the following error when trying to run the AppMap agent in a Docker Compose dev environment:

I think I understand what's going on here - the posix-socket module version (which I believe is a dependency of AppMap) is being installed for MacOS when I install it locally, but when I try to run it in a Docker container, the ELF headers are expected to be different.
There are a few similar issues out there, notably with bcrypt, and the solution is to run npm install inside of the Docker container rather than on the host machine so it installs the correct version. However, this really only helps when you're building your container. In development, where the project directory (including node_modules) is often mounted as a volume in a running container, there's not an easy way around this. At least not that I've found.
It's not necessarily your problem to solve as it's related to my dev environment, but I think my setup is fairly common so this may be something to look at in the future.
Anyway, I wanted to report this mostly in case others run into the same issue. If there's a better place to put troubleshooting information I'd be happy to write this up in a bit more detail and post it there instead, just let me know.
Thanks for all your work on AppMap, seems like a really cool project and I'm enjoying using it so far!
