The examples in the docs are auto generated from the code, so if you’re on these versions (bottom of the docs):
These docs were autogenerated using Makie: v0.16.1, GLMakie: v0.5.0, CairoMakie: v0.7.0, WGLMakie: v0.5.0
The examples should run fine.
If doing something with Meshes creates this error, you’ll need to make a minimal reproduceable example to figure out what’s going on!
