TextMeshPro Input Field throws errors in Play Mode

Package: TextMeshPro

-

How to reproduce:
1. Open attached project "Case_1203865" and load "SampleScene"
2. Open the Console window and enter Play Mode
3. Observe the Console window

Expected result: no errors are thrown
Actual result: errors are thrown upon entering Play Mode:
"MissingComponentException: There is no 'CanvasRenderer' attached to the "Caret" game object, but a script is trying to access it.
You probably need to add a CanvasRenderer to the game object "Caret". Or your script needs to check if the component is attached before using it."

Reproducible with: TMP 3.0.0-preview.1 (Unity 2020.1.0a15, 2020.1.0a16)
Not reproducible with: TMP 1.4.1 (2018.4.14f1), 2.1.0-preview.2 (2019.2.16f1, 2019.3.0f2, 2020.1.0a14)
Could not test with: Unity 2017.4.35f1 (no package)

Notes: Although the error concerns the "Caret" GameObject, the errors only stop if you disable the "Text Area" GameObject and not the "Caret" GameObject

  1. Resolution Note (fix version 3.0.0-preview.3):

    Fixed in package version preview.3 - 3.0.0

    I am experiencing the same issue on 2020.2.0a9 and 2020.2.0a8 . Similar to KTHROSE when I disable the TMP input fields at runtime then the error goes away.

    When updating to TMP preview version 3.0.0-preview.11 resolved for me.

    Sorry! I meant it appeared in preview1 3.3.0. I wasn't able to download preview3, I skipped right to 8.

    I can confirm this error did appear in preview.3 3.3.0 and was resolved when I downloaded preview.8. In my case, I was using a UI Panel and UI Dropdown without any trouble - then, I added TMP Input Field, and it caused this error on play. As per the reporter, I was able to to make it go away by deactivating it in the hierarchy.
