Upload progress only called once with multipart/form-data

[jgautheron]

I am uploading a file through multipart/form-data and getting only once the uploadProgress event, no matter how I tweak the interval.

"react-native": "~0.55.2",
"rn-fetch-blob": "git://github.com/joltup/rn-fetch-blob.git", // latest, updated just now

Hello I am having the same issue here.

I am using multipart/form-data to upload an image of ~2mb. I am testing on a very slow connection - the upload takes around 2 minutes. No matter what I set the "interval" value to the callback appears to trigger each time at exactly:

written: 10240 written: 81920

Does anyone have any idea how I can access the upload progress more frequently?

await RNFetchBlob.fetch(
          "POST",
          url,
          {
            Authorization: "Bearer access-token",
            "Content-Type": "multipart/form-data",
          },
          formData
        )
          .uploadProgress({ interval: 50 }, (written, total) => {
  console.log(
              "uploaded",
              written,
              total,
              Math.round((written / total) * 100) + "%"
            );
          })
          .then((resp) => {
            console.log("📤 -  Upload Completed");
          })
          .catch((err) => {
            console.log("📤 - Upload error: ", err);
          });
