Unity: ShaderGraph

Won't Fix

6.1.X

6.0.X

Steps to reproduce:

Create a new URP project.
Window > Package Manager > Shader Graph > Samples, import Feature Examples.
Observe the console.

Actual results: ~22 errors on import 6000.0.4f1 and below. ~51 errors 6000.0.5f1 and above - see [Internal link]. This ticket focuses on the ~22 errors.

Expected results: No errors.

Reproducible with versions: 6000.0.11f1(17.0.3), 2023.3.0b4 (17.0.2)

Not reproducible with versions: 2022.3.35f1 (14.0.11)

Can't test with versions: 2023.3.0b3 (17.0.2), 2021.3.40f1 (12.1.15), no Feature Examples available.

Tested on (OS): MacOS Intel - 12.7.4

Notes:

These are all reproducible as part of [Internal link], but have an earlier FAV.

The majority of the error messages are similar to:
