test_scripts.py fails on master due to invalid JSON generation in get_results_file_path()

[AdityaDagar000]

Summary

While working on issue #939, I noticed that all 5 tests in
tests/test_scripts.py fail on the current master branch
before any changes.

Root Cause

The get_results_file_path() function in tests/test_scripts.py
runs floss/main.py with --no static -j to generate a
results.json file. However the command fails and writes an
error message instead of valid JSON, causing all subsequent
script tests to fail with a pydantic ValidationError.

Steps to Reproduce

1. Clone the repo
2. Install dependencies with pip install -e ".[dev]"
3. Run python -m pytest tests/test_scripts.py -v

Expected Result

All 5 tests pass

Actual Result

All 5 tests fail with:
Invalid JSON: expected value at line 1 column 1

Environment

• OS: Windows 11
• Python: 3.11.9

@AdityaDagar000 I can't seem to replicate this (MacOS Tahoe, Python 3.11.14 (venv), pytest 8.4.1)

This is the results.json I get:
