Describe the bug
While applying the policy _index_template on an index, Open-search crashed on using the index.lifecycle.name in the API body. This setting is not available in open-search but it shouldn't crash the process and return with the exception.

This is occurring on a vanilla OS cluster even without index management plugin installed on the cluster.

Issue opened in Index Managem

There are few mocha tests which needs to be migrated to Jest.
Following test cases should be converted to jest.

Steps to convert :

• Move tests out __tests__ directory and append it with test.js / test.ts extension.
• Ensure tests are passing and are able to run via Jest.

╰─ yarn test:mocha
