In mongo/[site_scons|https://github.com/mongodb/mongo/tree/master/site_scons]/[mongo/|https://github.com/mongodb/mongo/tree/master/site_scons/mongo]pip_requirements.py,

    match = re.search(
        r"Package operations: (\d+) \w+, (\d+) \w+, (\d+) \w+, (\d+) \w+",
        poetry_dry_run_proc.stdout,
    )
    verbose("Requirements list:")
    verbose(poetry_dry_run_proc.stdout)
    installs = int(match[1])
    updates = int(match[2])
    removals = int(match[3]) 

int(match[1]) fails (match is set to None),  because regex fails to match "Package operations:", I found that poetry_dry_run_proc.stdout return some non pritable character like ESC  (try to write poetry_dry_run_proc.stdout to a file), there is a non pritable ESC char before ":", so match is None, and can't subscribe a Nonetype var.

poetry_dry_run_proc.stdout is something like : "�[39;1mPackage operations�[39;22m: ..."
