I hit the `panic: runtime error: index out of range [0] with length 0` during tests, and I guess it's a code logic error, and it just appeared accidentally.

    Unknown, it's an accidental error, but I think it can be reproduced in the unit test: Add a unit test to test the condition field in the DataGather CRD is None.

    1. Add a unit test to test the scenario that the condition field in the DataGather CRD is None.
    

    1. The unit test fails due to a runtime error.

    1. The unit test passes.

    This problem should be easier to reproduce and test in the unit test, so we won't cover it in the e2e test.
