Steps to reproduce this

Running any code with TESS as the shape mode (or anything that triggers this under the hood, like bezierVertex) in WebGL shows this warning:

You must first call texture() before using vertex() with image based u and v coordinates 

Some example code that will trigger this:

function setup() {
  createCanvas(400, 400, WEBGL);
}

function draw() {
  background(220);
  
  strokeWeight(3)
  beginShape(TESS)
  vertex(-50, 0)
  vertex(-25, -50)
  vertex(25, 50)
  vertex(50, 0)
  endShape()
}

This is because TESS supports texture coordinates as of #5830, but it always runs them through libtess. The warning is harmless, but just annoying, as it clogs the console.
