AWS Lambda [ERROR] DistributionNotFound: The 'jsonschema' distribution was not found and is required by the application

[Siddiqa Jaffer]

We're trying to run jsonschema 3.0.2 on the AWS Lambda Python 3.7 environment. We're getting the following error: 

The following link suggested to go back to using  version 2.6.0 which works but is there a reason why 2.6.0 works and 3.02 doesn't? Will there be fix made available in jsonschema for this issue?
