AGI cannot be started

Asterisk Asterisk APIs

I created an AGI script and defined it in extensions.conf. However, I get the following error in the Asterisk CLI. I have tried many methods but it hasn’t been resolved. What could be the problem?

ag2_script.py

import sys
import os

def main():
    print('AGI START')
    agi_env = {}
    for line in sys.stdin:
        line = line.strip()
        if not line:
            break
        key, value = line.split(': ')
        agi_env[key] = value
        print(f"AGI Variable: {line}", file=sys.stderr)

    print('ANSWER')
    print('STREAM FILE hello-world ""')
    print('HANGUP')

if __name__ == '__main__':
    main()

Additionally, is this normal?
