What would cause this error,? "/var/task/prefect/context.py501 UserWarning: Failed to create the Prefect home directory at /home/sbx_user1051/.prefect /var/task/prefect/context.py501 UserWarning: Failed to create the Prefect home directory at /home/sbx_user1051/.prefect"

I think permissions - you need to set PREFECT_HOME to where the lambda can write

That seem to work, I set PREFECT_HOME to '/tmp/prefect'. However none of the logs are showing up in cloudwatch, as they are with regular logs outside of Prefect.
