Hey @MasumRab - I've reviewed your changes - here's some feedback:

• The change from allow_population_by_field_name to validate_by_name isn’t a valid Pydantic config option—please revert or correct to maintain alias support.
• Commenting out all calls to _execute_async_command effectively disables the NLP subprocess flow—consider mocking or restoring it instead of permanently removing execution paths.
• The test for ActionItemExtractor has been stubbed out and no longer exercises real behavior—please restore a proper instantiation and assertions to keep the test meaningful.

<issue_to_address>
Incorrect Config attribute for alias population

In Pydantic v2, use 'populate_by_name' instead of 'validate_by_name' to enable alias-based population.

Unreachable code after return statement

Please remove or refactor the code after the return statement, as it is now unreachable.

Catching wrong exception for missing NLTK resources

nltk.data.find raises LookupError, not ErrorMessage. Update the exception handling to catch LookupError for missing resources.

Critical: Tests in this file appear to be disabled.

Please clarify the 'debug' reasons for disabling these tests and provide a plan to restore them. If the root cause is related to pytest hanging or module dependencies, resolving that should be prioritized to maintain test coverage.
