⚡️ Describe the Bug

Running the Dockerized app fails immediately because Union is used in src/main.py but is not imported.

👣 Steps to Reproduce

1. Build and start the containers
2. Run:

   make exec
   

3. See error NameError: name 'Union' is not defined

📉 Expected Behavior

The app should start normally without crashing on a missing import.

🖥️ Environment Information

OS: macOS
Docker/Compose Version: Docker 29.2.1
Ollama Model used: mistral:latest

Traceback (most recent call last):
File "/app/src/main.py", line 14, in
def run_pdf_fill_process(user_input: str, definitions: list, pdf_form_path: Union[str, os.PathLike]):
^^^^^
NameError: name 'Union' is not defined
make: *** [exec] Error 1

🕵️ Possible Fix

Add in the top of the /src/main.py:
from typing import Union

Hi! @qngu0461 I was reviewing the repository while preparing for GSoC and came across this issue.

It looks like Union is used in the type annotation of run_pdf_fill_process() in src/main.py but isn’t imported, which causes a NameError when running the Docker environment with make exec.

I’d be happy to work on fixing this by adding the missing from typing import Union import to ensure the application starts correctly.
If it’s okay, could this issue be assigned to me?

Hi @Mahendrareddy2006, thank you for your comment, but i have already fixed that bug successfully by add in the top of the /src/main.py: from typing import Union

@qngu0461 i raised this issue a few weeks ago in #135 , pls avoid creating redundant issues

Hi @Cubix33 , I raised this based on my own reproduction in a different environment. Your report came from a different environment does not automatically make this redundant. Maintainers can decide whether it should be treated as a duplicate
