Fail to load login page!

Describe the bug
After much effort and trying different scenarios, I was able to run the python3 server.py --insecure --build command without error; but unfortunately, the login page (http://localhost:8888) still did not open and gave a 500 error.

To Reproduce
Steps to reproduce the behavior:

1. Install OS requirement (Python 3.13, nodejs 23.0, ...)
2. Install Caldera as Installation guide
3. Install dependencies (requirements.txt)
4. RUN server.py

Expected behavior
show caldera login page and can use it by users.
