To reproduce the issue

• Optional: Install podman and change common.sh if you want to use podman to build and run the container.
• Build and run the image with: ./build.sh && ./run.sh
  • This should drop you into a neovim process which installs the necessary language servers to reproduce this issue.
• Wait for Mason to update it's package list and then for ansible-lint to finish installing.
  • This takes about 15-20 seconds on my machine, so patience is a virtue.
• Press 'q' to close the Mason menu.
• Run :AleInfo or any other diagnostic commands necessary.
• Exit out of the editor with :wq
• You should see the error in your terminal, similar to:

[me@host ale_issue]$ ./run.sh
