Preprocessing script logs sagemaker model monitoring.

While creating a monitoring job for an endpoint I attached a preprocessing script to flatten the captured data but my script fails with an invocation error. Furthermore, I am unable to see any logs from the preprocessing script in the cloud watch just an innovation error in monitoring job logs.
Tried writing into the '**/opt/ml/output/message**' file after encoding the logs in UTF-8 but could not see any logs from the script in monitoring job logs.

Start by reproducing the SageMaker model monitoring job with the attached preprocessing script and inspect the monitoring job logs in CloudWatch. Check whether writing UTF-8 encoded output to /opt/ml/output/message is supported and whether the invocation error identifies the script failure. Done means the preprocessing script runs successfully and its diagnostic logs are visible in the documented monitoring logs.
