Expected Behavior

Display DaemonSet Guide.

Current Behavior

Throws out unknown error

Reproduction Steps

Running Centralized Logging with OpenSearch Workshop

Possible Solution

The root cause is the artifact "s3://aws-gcr-solutions-assets.s3.amazonaws.com/{solution_version}/flb_version.txt" missing when solution_version =workshop_v2.1.1.

It could be a bug only apply for workshop. But it could be resolved by adding error handling at lines 433 of "/source/constructs/lambda/api/app_log_ingestion/flb
/flb_builder.py
