Problem summary
Type mismatch error when trying to bake a NetworkMaterial with parameters that are promoted and connected to previous shading nodes using UsdMaterialBake node
Customer reported version
Katana 6.0v3
Customer reported platform
Windows 10
Steps to reproduce
1) Download and open the example scene attached as 'usdbake_fail.katana'.
2) Under the UsdMaterialBake node, press 'Write' and observe the error displayed in the command prompt.
Error in 'fnInternal_v22_05__pxrReserved__::UsdStage::_SetValueImpl' at line 6046 in file W:\jenkins-devops0\d35eea\1\USD_src\pxr\usd\usd\stage.cpp : 'Type mismatch for </root/materials/andre_strap_MAT.inputs:base>: expected 'float', got 'void''
3) Fix the error by diving into the 'material' folder and the NetworkMaterialCreate node.
4) From there, disconnect the two shading nodes.
5) Successfully bake the material by going back to UsdMaterialBake and pressing 'Write'.
