    Since upgrading to @4.2.0, I'm getting:

    "Warning: Each child in a list should have a unique "key" prop.

    Check the render method of `KendoReactGrid`. See https://fb.me/react-warning-keys for more information.
        in tr (created by KendoReactGrid)
        in KendoReactGrid (created by BatchesGrid)
        in BatchesGrid (created by Context.Consumer)"

    (This is a snippet of the callstack.)

    I haven't been able to reproduce in StackBlitz.  I'll try to do more troubleshooting next week.  I wasn't sure if you guys were getting it on your end or not.

    Hello, Kyle,

    We have a known issue for that warning when the Grid has no data:

    If this is the same case, please monitor the GitHub item for updates.

    NICE!

    First, glad to know I wasn't wrong in that it's only since version 4.2.0.

    Second, I didn't notice it was only for a No Records Found.

    Glad you know about it.
