Hi @klmuthu I think you are missing the cdk.json file. When deploying, I receive this error:
--app is required either in command-line, in cdk.json or in ~/.cdk.json

Also, please include a completed example-pattern.json file

Hi @ellisms I updated the readme to use --app with cdk deploy. Also, updated the readme to create python virtual environment to avoid version conflicts. I didnt create cdk.json just to keep the repo small. Let me know if this deploys now. Please note the Redshift cluster has to be created as a prerequisite and the .env should be updated with the arn. The instructions is in the readme.

Thanks @klmuthu . I'm able to deploy the solution, but when testing, I'm getting the following error in the Lambda function:
[ERROR] Runtime.ImportModuleError: Unable to import module 'redshiftapi': No module named 'redshiftapi'

Hi @ellisms, Thanks for testing. There was a copy/paste error. I fixed and tested it. Please try again.

Thanks. The function now executes, but returns this error:
"body": "{\"error\": \"FATAL: database \\\"sample-data-dev\\\" does not exist\"}"
The database does exist and I can connect via the Console.

Hey @ellisms, I believe it could be because the db name not correct. You used hyphen instead of underscore in the db name. The name should be sample_data_dev. Can you give this a try?

Requesting a few minor changes.

Good catch! Tested and it is working. Left a few feedback items for review/updates.
