Steps to reproduce this

Steps:

1. Draw a shape with vertexProperty between each vertex
2. Make sure you pass a single value as the property (e.g. 0) as opposed to an array (e.g. [0])

This throws the error Error: Can't convert 0 to array!. If you use an array, there is no error. It should be converting to an array under the hood, but I must have messed that up in the shapes refactor.

Snippet:

function setup() {
  createCanvas(400, 400, WEBGL);
  
  const pts = []
  for (let i = 0; i < 50; i++) {
      pts.push(createVector(random(width), random(height)))
  }
  
  const snake = buildGeometry(() => {
    noFill()
    beginShape()
    for (const [i, { x, y }] of pts.entries()) {
        vertexProperty('length', i/(pts.length-1))
        splineVertex(x, y)
    }
    endShape()
  })
}
