System Information
Operating system: Windows-10-10.0.19041-SP0 64 Bits
Graphics card: NVIDIA GeForce RTX 3070 Laptop GPU/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 472.12

Blender Version
Broken: version: 3.0.0 Alpha, branch: master, commit date: 2021-10-21 21:23, hash: d9ebe25a0c
Worked: version: 2.93.5
Caused by 0803119725

Short description of error
I was using a 2.93.5 project to render in 3.0, and I found that the animation of emission strength was recognized as transmission roughness animation.
I then opened a new project and add some EmissionStrength animation to the cube material, and open it in 3.0, and I got a cube with TransmissionRoughness animation.
and the last key value of the animation was correctly inherited to the 3.0, but with no animation (not any keyframes) for it was applied to TransmissionRoughness.

Exact steps for others to reproduce the error

Create a project in Blender 2.93.5
Add some animation to EmissionStrength of the material of the cube
Save and open it in Blender 3.0

test.blend
I uploaded the .blend file, you may want to check it in both 2.93.5 and 3.0 and then compare the difference.

This is caused by the animation data targeting node properties by index. In this case, it animates nodes["Principled BSDF"].inputs[18].default_value. I have a patch ready.
