Multiple issues with docker build

Hello
I've been having multiple issues running the plexrequest docker build (pulled from the repo).
Starting the application works fine, but search is completely broken as well as trying to pull the plexpass token.
For example, when searching for a movie, this is shown in the logs:

It seems like the build is missing some files, such as /built_app/version.txt

This may also be a source of some of the other issues. Can anyone else confirm?
Using the standard docker-compose file.

Inspect the Docker build and standard docker-compose setup, then read server/methods/admin/version.js where the missing /built_app/version.txt is accessed. Run the image and check whether the built application contains the reported file and whether the logged search and Plexpass token failures remain. Done means the image builds with required files and those operations no longer produce the reported errors.
