`packetLoss` endpoint has CORS set to `speed.cloudflare.com`

[96imranahmed]

Hi there, the default config is failing because the packetLoss test queries https://speed.cloudflare.com/turn-creds

However, the CORS policy for this page is set to only accept cloudflare domains (e.g., access-control-allow-origin: speed.cloudflare.com)

A workaround is to remove packetLoss calculations from the test, but I'd love to be able to also use packetLoss stats in the reporting on my app!

Running the code below in react gives Cors error:

import SpeedTest from '@cloudflare/speedtest';

new SpeedTest().onFinish = results => console.log(results.getSummary());

Access to fetch at '[https://speed.cloudflare.com/turn-creds](vscode-file://vscode-app/Applications/Visual%20Studio%20Code.app/Contents/Resources/app/out/vs/code/electron-sandbox/workbench/workbench.html)' from origin '[http://localhost:3000](vscode-file://vscode-app/Applications/Visual%20Studio%20Code.app/Contents/Resources/app/out/vs/code/electron-sandbox/workbench/workbench.html)' has been blocked by CORS policy: The 'Access-Control-Allow-Origin' header contains the invalid value 'speed.cloudflare.com'.

@96imranahmed how did you do the workaround for packetLoss??

[96imranahmed]

Sorry I wasn't clear - I don't have a solution for getting a packetLoss metric. I just ignore the test entirely by removing it from the list of default measurements that are run when you make a test.

    { type: 'latency', numPackets: 1 }, // initial ttfb estimation
    { type: 'download', bytes: 1e5, count: 1, bypassMinDuration: true }, // initial download estimation
    { type: 'latency', numPackets: 20 },
    { type: 'download', bytes: 1e5, count: 9 },
    { type: 'download', bytes: 1e6, count: 8 },
    { type: 'upload', bytes: 1e5, count: 8 },
    { // Remove this line
      type: 'packetLoss',
      numPackets: 1e3,
      batchSize: 10,
      batchWaitTime: 10, // ms (in between batches)
      responsesWaitTime: 3000 // ms (silent time after last sent msg)
    },
    { type: 'upload', bytes: 1e6, count: 6 },
    { type: 'download', bytes: 1e7, count: 6 },
    { type: 'upload', bytes: 1e7, count: 4 },
    { type: 'download', bytes: 2.5e7, count: 4 },
    { type: 'upload', bytes: 2.5e7, count: 4 },
    { type: 'download', bytes: 1e8, count: 3 },
    { type: 'upload', bytes: 5e7, count: 3 },
    { type: 'download', bytes: 2.5e8, count: 2 }
