Errorreport: “node bump” error on V3D 4.9.1 for Blender in Browser

In the console my scene is throwing a few of these, I assume it may be some bump nodes in my materials, but it looks like a Verge Shader error :

v3d.js:1 v3d.WebGLProgram: shader error: 0 35715 false gl.getProgramInfoLog Fragment shader is not compiled.
