A simple workaround for me was to not use structs in the shader but use simple types, being a newbie I didn't want to tangle with using buffers for the uniforms.

like shader: uniform float time ;
and then: gl.glUniform1f(uniformId, time);

But I'd be interested to learn how to do that struct/buffer thingy :-)
