Can't set axis label sizes

plotly.js

Trying this layout to change size

Plotly.relayout(figurecontainer,{
    scene: {
        aspectmode:"manual",
        aspectratio:{
            x: 1,
            y : .8,
            z: .5
        },
        zaxis: {
            showgrid: false,
            zeroline: false,
            showline: true,
            title: "u (a.u.)",
            font:{
                family:"Times New Roman",
                size : 100
            }
        },
        yaxis: {
            showgrid: false,
            zeroline: false,
            showline: true,
            title: "R (a.u.)",
            font:{
                family:"Times New Roman",
                size : 100
            }
        },
        xaxis: {
            showgrid: false,
            zeroline: false,
            showline: true,
            title: "r (a.u.)",
            font:{
                family:"Times New Roman",
                size : 100
            }
        }
    },
})

But the axis label size is not changing

Try setting tickfont.size instead of font.size (which isn’t a valid axis attribute)
