(Case 1188666) UI stops working if PlayerInput/InputSystemUIModule share inputactions asset

The UI stops working, if the PlayerInput and InputSystemUIModule Components share an inputactions asset. Tested with 2019.3.0b4 and InputSystem-preview-1.0.0.

A video is attached to bug-report 1188666. The test project can be found attached to this post, as well as in the bug-report.

Reproduce

• Open attached project
• Open Scene.unity
• Press Play
• Hover mouse pointer over the two buttons
• Notice they play their highlight effect
• Press Stop
• Select PlayerInput gameobject and enable it
• Press Play
• Notice UI does not highlight anymore
• Press Stop
• Duplicate MyInputActions.inputactions
• Assign duplicated inputactions to PlayerInput
• Press Play
• Notice UI highlight works again

Actual
When the PlayerInput Component and InputSystemUIModule Component share the same inputactions asset, the UI stops working.

Expected
I expected the UI to continue to work.
Sharing inputactions assets should be supported, I guess?

 

I have this same error in my project. I just updated my project to using 2019.2.8f1, and using Input System Preview 1.0.0.

When I try to click on the UI element, in this case a button with the mouse I see this error:
