New to custom code functions: Python default example doesn't work.

Hi, I’m new to using the custom code function and when I test the default code block it gives when selecting python as the language it fails, but when I test with the custom JS block it works.

The JS code is here:

exports.main = async (event, callback) => {
/*****
Use inputs to get data from any action in your workflow and use it in your code instead of having to use the HubSpot API.
*****/
const email = event.inputFields[‘email’];
/*****
Use the callback function to output data that can be used in later actions in your workflow.
*****/
callback({
outputFields: {
email: email
}
});
}

The python code is here:

def main(event):
email = event[“inputFields”][“email”]
# Return the output data that can be used in later actions in your workflow.
return {
“outputFields”: {
“email”: email
}
}

The python code fails with this message:

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

@CGrove0 - this may seem like a stupid question, but have you explicityly defined ‘email’ as an input property to the custom cose workflow step? The name must be an exact match to that input definition.
