[BUG] RollupInterceptorIT integration test is failing

[Tarun-kishore]

What is the bug?
The RollupInterceptorIT integration test is failing due to a mismatch in the expected error message order when validating rollup search failure. The actual message contains the same fields, but the order of "missing field" entries is not deterministic.

How can one reproduce the bug?

1. Run RollupInterceptorIT.test roll up search in the Index Management module.
2. Test fails with different order of missing fields in the error string.

What is the expected behavior?
The error message should clearly report the required missing fields, but the test should not be sensitive to their order if all required fields are present in the message.

What is your host/environment?
