Standalone works, WebGL doesn't; shader problem?,Standalone version works, WebGL doesn't. Shader problem?

The standalone version for MacOs works without any problem. When I change the build to webGL the entire game turns pink on launch. I think this is a shader problem. I tried resetting my shaders countless of times but I don’t get it to work.

Does anyone know what to do?
