onUploadProgress is not working as expected ?

I’m having the same issue!

Here’s a GIF to demonstrate it:

My code looks similar to this:

// Progress
 var config = {
     onUploadProgress: function (progressEvent) {
          let percentCompleted = Math.round((progressEvent.loaded * 100) / progressEvent.total)
          console.debug('onUploadProgress called with', arguments, 'Percent Completed:' + percentCompleted)
     }
}

// Call API
axios.get(endpoint, data, config)

What browser are you using? Are you sure it supports progress events?

I’d also try using something like:

const config = {
    onUploadProgress:function (progressEvt) {
        console.log('onUploadProgress called with', arguments);
    }
};

So you will always show a message and it will be easier to debug.
