When trying to configure vpc_config you get the following error
Jets version 2.3.18
Error message in cloudformation:
The provided execution role does not have permissions to call CreateNetworkInterface on EC2 (Service: AWSLambdaInternal; Status Code: 400; Error Code: InvalidParameterValueException; Request ID: 111a6a04-90b6-4b0f-9611-d57e66c56f4d; Proxy: null)
Solution:
Go to your lambda function and look for the executing role. This should be auto generated by jets. Add the policy named AWSLambdaVPCAccessExecutionRole
