Unable to set PathExpressionArray in Python

I’m trying to create an asset with a Path Expression array
I thought this code should work, but it errors out

array = prim.CreateAttribute("array", Sdf.ValueTypeNames.PathExpressionArray, custom=False) 

array.Set([Sdf.PathExpression("Hello"), Sdf.PathExpression("World")])

The error is

Error in 'pxrInternal_v0_24__pxrReserved__::UsdStage::_SetValueImpl' at line 6723 in file /Users/dhruvgovil/Projects/usd/pxr/usd/usd/stage.cpp : 'Type mismatch for </root.array>: expected 'VtArray<SdfPathExpression>', got '__1::vector<VtValue, __1::allocator<VtValue>>''

Just wondering if anyone has set PathExpressions in an array and knows how to wrap it properly in Python to get it across the binding boundary?

I don’t see a corresponding array type in the Vt module either. Is this case unsupported via Python?

Yeah that sounds like a converter-registry omission (though the registry needs to be updated in sdf, not vt, since vt is lower level) - would you file an Issue, @dhruvgovil ?
