The root cause for the failure seems to be a combination of the environment and dependencies.
Infrastructure setup is done using the latest aws-cdk which is running on a node 10 environment. This configuration is causing failures similar to the ones mentioned here and here.

One of the solutions is to upgrade to node 16. With the current setup of the existing agent image we are restricted with an older node version.

Upgrading to a newer node version will help resolve this issue

Submitted a request for an image with node 16 support - opensearch-project/opensearch-build#2211
