UBO - UniformBufferObject with onBeforeCompile on MeshStandardMaterial won't compile

Hey there!
I’m extending / updating an existing material (MeshStandard one) using the onBeforeCompile method.
So far so good, done plenty of times but now i’m using uniformsGroup and apparently i cannot bind them onBeforeCompile for some reasons?
I’ve used uniformsGroup a lot in shader materials, never on existing ones.

 material.onBeforeCompile = (shaders => {
            shaders.uniformsGroup = [globalUniforms]
            shaders.vertexShader = shaders.vertexShader.replace(
                `#include <common>`, `
                    ${globalUBO}

                    #include <common>
                `
            )

gives

[.WebGL-0x138005baf00] GL_INVALID_OPERATION: It is undefined behaviour to have a used but unbound uniform buffer.

Nothing really helpful :thinking_face:

The issue apparently might be not the binding itself but definition in the shader because if i remove the ${globalUBO} string it doesn’t throw an error (but clearly doesn’t work)
I tried to write it manually too instead of using a variable but still the same issue

Any idea?
