Shader Graph's preview can't compile when the first output is not a Vector, Matrix, or Boolean type
How to reproduce:
1. Open the attached “ShaderGraphIssue” project
2. Open the “New Shader Sub Graph” asset
3. Observe the area around the Output node
Expected result: There is no exclamation mark near the Output node
Actual result: An exclamation mark near the Output node produces this error when hovering the cursor over it: "Validation: Preview can only compile if the first output is a Vector, Matrix, or Boolean type. Please adjust slot types". A preview with missing textures is also present
Reproducible with: 10.10.0 (2020.3.39f1), 12.1.7 (2021.3.11f1), 13.1.8 (2022.1.20f1), 14.0.3 (2022.2.0b10), 15.0.1 (2023.1.0a12)
Reproducible on: Windows 10
Note: The same issue can be observed if the Output slot is Texture2D, Texture2D Array, Texture3D, Cubemap, or Gradient

Resolution Note:
This is working as intended. Sub Graph will use the first output, regardless of type, to compile the preview. However, the preview will only successfully compile if it is a numeric type (as seen in the error message).
In the example project provided, the error shown is valid because the first input is a Sample State and it's expecting a Vector, Matrix, or Boolean.
