ShaderGraph error is thrown when the first subgraph output isn't previewable

Reproduction steps:
1. Open the attached “BugRepro” project
2. Open the “Assets/New Shader Sub Graph.shadersubgraph“ subgraph
3. Change the type of the output to Sampler State
4. Observe the Console window

Expected result: No errors are thrown
Actual result: “Shader error in 'Sub Graphs/Master': cannot convert from 'int' to 'struct SurfaceDescription' at /(172) (on d3d11)” error is thrown

Reproducible with: 2022.1.0a1, 2022.3.60f1, 6000.0.44f1, 6000.1.0b12, 6000.2.0a8
