Greasepencil weight_get and vertex_group.blendShort description of error
Exact steps for others to reproduce the error
See attached blend.
I've included 3 examples:
A try and except script to get the vertex weight of 4 strokes which fails on 3 upper vertex group indices.
A script that sets the vertex weight of all points to 0 and after which when you weight paint manually and rerun the first script, you get the vertex weight successfully
A script where you create the vertex_group and set them with a specific value successfully, but when you try to read them back with weight_get, it results with a vertex group index out of range

Changed status from 'Needs Triage' to: 'Confirmed'
The problem is checking the number of available weights.
