TypeError: in typeassert, expected Type, got a value of type Ptr{Nothing}

[SimonDanisch]

Julia 1.6
JuliaInterpreter v0.8.14

MWE:

using JuliaInterpreter, GLFW, ModernGL

function gen_buffers()
    result = GLuint[0]
    ModernGL.glGenFramebuffers(1, result)
    id = result[1]
    if id <= 0
        error("glGenFramebuffers returned invalid id. OpenGL Context active?")
    end
    return id
end

function test()
    w = GLFW.Window()
    gen_buffers()
end

@interpret test()
