Question

What's wrong with this Python code?

I’m trying to use Code by Zapier to extract some hexadecimal characters from an input URL, concatenate them with hyphens, then generate an output URL. Using Zapier’s AI code-gen tool, I got this:

import re

# Extract the original URL from the input data
original_url = input_data["original_url"]

# Define a regular expression pattern to match the hexadecimal characters in the original URL
pattern = r"name_([^/_]+?)_([^/_]+?)_([^/_]+?)_([^/_]+?)_([^/_]+?)/master\.m3u8"

# Extract the hexadecimal characters from the original URL using the defined pattern
match = re.match(pattern, original_url)

# Join the extracted hexadecimal characters with hyphens
uuid_like = "-".join(match.groups())

# Define the base URL for the output
base_url = "https://vod.chdrstatic.com/transcode/"

# Concatenate the base URL, the extracted and joined hexadecimal characters, and the file extension to form the final output URL
output_url = f"{base_url}{uuid_like}/{uuid_like}.mp4"

# Store the final output URL in a dictionary with the key as "output"
output = {"output": output_url}

To my non-coder eyes, this looks about right, but whenever I test it, I get the following error:

Traceback (most recent call last): File "<string>", line 20, in the_function AttributeError: 'NoneType' object has no attribute 'groups'

 

Any ideas what’s up or what I need to fix?
