Custom Coded Action - Parse Property for Custom Object ID

[JLittle2]

I have a form that collects vins and other info from users. These users need to be able to list an unlimited number of vins, so I'm using a multi-line property to allow them to input as many as needed (one per line).

Here's the thing, we use vin as the unique identifier of our custom object "Vehicles". I need a way to separate the multi-line field into individual vins, and create a Vehicle record for each. I know that with custom coded actions I can parse through the collected vins and add them to a list, but is it possible to create a Vehicle record for each within the same action? 

Thanks y'all!

Attached is the code I've pulled together. I'm getting this lambda error:

LAMBDA_WARNING: Unhandled exception. The most likely cause is an issue in the function code. However, in rare cases, a Lambda runtime update can cause unexpected function behavior. For functions using managed runtimes, runtime updates can be triggered by a function change, or can be applied automatically. To determine if the runtime has been updated, check the runtime version in the INIT_START log entry. If this error correlates with a change in the runtime version, you may be able to mitigate this error by temporarily rolling back to the previous runtime version. For more information, see https://docs.aws.amazon.com/lambda/latest/dg/runtimes-update.html
[ERROR] TypeError: main() missing 1 required positional argument: 'context'

File "/var/task/hubspotHandler.py", line 6, in hubspot_handler
return file.main(event)

Any help would be appreciated!

This is the code that ended up working for me. I just got rid of the context. Also, turns out, when you use test action in a custom coded action it can't fetch associated object properties, so I had to test the whole workflow for it to pull all the information. But it works! Hopefully this helps someone else in the future.
