Report not getting saved when running the command using python

[ManishAradwad]

I'm calling pytest using python in my code as follows:

# Construct the command
command = f'cd /d "{file_dir}" && python -m pytest --json-report "{test_file_name}" -v --cov="{repo_path}" --cov-report term --cov-report html:"{repo_path}/htmlcov"'
# Run the command
process = subprocess.Popen(
    command,
    stdout=subprocess.PIPE,
    stderr=subprocess.STDOUT,
    universal_newlines=True,
    shell=True,
)

I'm getting this in the text report generated, but there is no .report.json file getting saved.

--------------------------------- JSON report ---------------------------------
report saved to: .report.json

Can someone help me with this plase?
