Solution:

Ensure that the Project Code, Integration Code, and Version are correctly mapped in the invoke action using a Lookup.

Steps:

1. Open the integration where the local call is being made.
2. Use a Lookup to dynamically fetch the Project Code, Integration Code, and Version.
3. Ensure the endpoint URL is correctly formed using these values.
4. Verify that the lookup values match the actual integration details in the project.
5. Save, activate, and test the integration again.

This ensures dynamic mapping and avoids hardcoded values, resolving the 404 error.
