ButtonWithTwoModifiers: Cannot find public field 'Modifier 1'

Unity Engine
1

After adding a ButtonWithTwoModifiers in my InputActions asset, I get this error

InvalidOperationException: Cannot find public field ‘Modifier 1’ used as parameter of binding composite ‘UnityEngine.InputSystem.Composites.ButtonWithTwoModifiers’ of type ‘UnityEngine.InputSystem.Composites.ButtonWithTwoModifiers’

I checked the doc:
https://docs.unity3d.com/Packages/com.unity.inputsystem@1.0/api/UnityEngine.InputSystem.Composites.ButtonWithTwoModifiers.html

So manually changing the field name

""name"": ""Modifier 1"",

to

""name"": ""modifier1"",

in the generated file does solve the problem, but is there a way to not have to do this?

I just had to do this rename as well, thank you for the tip!

Same here: I googled the error message and arrived here, which fixed it for me. Thanks!

As an extra data point: I got into this situation by changing a 1-modifier binding to 2-modifier. The old binding was now used as modifier-2, so I swapped modifier-2 and binding.

Still happening with 1.7.0, and this time it happens with the TwoModifiersComposite

Anyone submitted a bug report for this?

Not seeing this fixed in the changelog
