"Trying to access shader snippet -1" is thrown when accessing Pass.SourceCode for a GrabPass pass type

Shader System


How to reproduce:
1. Open the attached "ShaderAPI" project
2. Select the "Assets -> Internal -> New Shader Analyzer" Asset
3. Right-Click on the Asset icon in the Inspector
4. Select Compile
5. Observe the Console log

Expected result: The Shader variants compiled successfully without any errors
Actual result: The Shader variants fail to compile. "Trying to access shader snippet -1, but it was not found." error is thrown

Reproducible with: 2020.3.24f1, 2021.2.5f1, 2022.1.0b1
Couldn't test with: 2019.4.33f1 (some ShaderUtil and ShaderData.Pass definitions are not present)

  1. Resolution Note (fix version 2022.2):

    Fixed in 2022.2.0a5
    Accessing the source code for a GrabPass type pass should now return an empty string. In addition, IsGrabPass was added so you can query this state yourself.
