[BUG] BASE_URL breaks yarn build

[LandStander27]

Environment

Self-Hosted (Docker)

System

Fedora-Server 6.11.10, Docker 27.3.1

Version

3.1.1

Describe the problem

When starting up the container with BASE_URL not set, (set to ./), the yarn build finishes fine and there are no errors. However, when I have BASE_URL set (/dash) I get a Failed to compile with 1 error.

Going to http://{domain}/dash returns with Error: ENOENT: no such file or directory, stat '/app/dist/index.html'. However, going to the root (http://{domain}/) shows the loading screen.

Additional info

docker-compose.yml

services:
  dashy:
    image: lissy93/dashy:latest
    restart: unless-stopped
    environment:
      - VUE_APP_healthcheck_key=secret
      - VUE_APP_passwd=secret
      - NODE_ENV=production
      - VUE_APP_STARTING_VIEW=home
      - IS_DOCKER=true
      - BASE_URL="/dash"

    ports:

    volumes:

  monitoring:

    restart: always
    pid: host
    build:
      network: host
    privileged: true
    ports:
      - 61208:61208
    volumes:
      - /var/run/docker.sock:/var/run/docker.sock
      - /etc/os-release:/etc/os-release:ro
    environment:
      - "GLANCES_OPT=-w"

Parts of the error that seem even somewhat useful (everything else looks like the HTML for the crash page):

This is likely caused by the app source not being found at the current domain
