renderToBufferSync is undefined

[daveteu]

const chartJsFactory = () => {
    const Chart = require('chart.js');
    require('chartjs-plugin-datalabels');
    delete require.cache[require.resolve('chart.js')];
    delete require.cache[require.resolve('chartjs-plugin-datalabels')];
    return Chart;
}

 const canvasRenderService = new CanvasRenderService(1200, 800, (ChartJS) => {


            ChartJS.defaults.global.animation = false;
            ChartJS.defaults.global.responsive = false;
            ChartJS.defaults.global.defaultFontFamily = 'NUNITO';


        }, 'SVG', chartJsFactory);
        canvasRenderService.registerFont('./fonts/NunitoSans-Regular.ttf', { family: 'NUNITO' })
const stream = canvasRenderService.renderToBufferSync(chartOptions,'image/svg+xml')

res.write(stream);
res.end();

While trying to render a SVG, stream is undefined. Already installed imagemagik as documented. I am able to render image/png effortlessly.

Found the problem.

Documentation says "PDF" or "SVG", however, the value for type should be "svg" or "pdf" in small letters.

Thanks for the feedback, I'll look into adding a .toLowerCase() for others to avoid this👍
