Bug report

This is a potential bug on the docker image (pulled from the official docker image

What is the current behavior?
When running:

sudo docker run --rm -v /home/turtyo/[a path]/doc_comment_test:/game -v /home/turtyo/[a path]/doc_comment_test/doc:/output gdquest/gdscript-docs-maker:latest /game -o /output

I am getting:

Checking parameters
Copying collectors to project directory
Generating reference json data...
Done.
There was an error generating the reference from Godot. The file /game/reference.json was not found.

What is the expected behavior?

The /game/reference.json should exist, or it does but not in the correct place, it should be where the script expect it to find

Tell us the steps to reproduce the bug, and if possible share a minimal demo of the problem.

• sudo docker pull gdquest/gdscript-docs-maker
• sudo docker run --rm -v /home/turtyo/[a path]/doc_comment_test:/game -v /home/turtyo/[a path]/doc_comment_test/doc:/output gdquest/gdscript-docs-maker:latest /game -o /output

The project I'm doing this one (basically a copy of the Godot's example on documenting code, nothing fancy)

Here is the godot.log file i'm getting after running the docker instance:

I'm noticing the container runs the 3.3.2 Godot version, but my project is in version 4.2.
There might a compatibility issue there, but I did not find the container that runs the 4.2 version (if it exists, please link it to me so i can test if that works or not)

Edit: this might be the exact same problem as #95

This project is for Godot 3. You won't be able to run it with Godot 4. I'll update the readme to specify that it doesn't work with Godot 4.

[Turtyo]

I see, it was a bit confusing since Godot 4 was mentioned multiple times in the previous README
Thank you for updating @NathanLovato
Maybe you should take a look at #51 since they seem to be trying to make it work on Godot 4 versions too
