Null responseBody when upload from ios device

[APZelos]

I try to upload a file from an actual ios device but I get a null responseBody, but when I try to upload from a simulator everything works as expected.

Here is my code:

async function fileBackgroundUpload(filePath) {
  console.log('[UPLOAD] file path', filePath);

  const url = 'my-endpoint';

  const uploadOptions = {
    headers: {
      Accept: 'application/json',
    },
    url,
    path: filePath.replace('file://', ''),
    method: 'POST',
    field: 'file',
    type: 'multipart',
  };
  console.log('[UPLOAD] options', uploadOptions);

  let uploadId;
  try {
    uploadId = await Upload.startUpload(uploadOptions);
    console.log(`[UPLOAD] background upload id: ${uploadId}`, {
      filePath,
    });
  } catch (error) {
    console.log('[UPLOAD] error while uploading file', error);
    throw error;
  }

  const promise = new Promise((resolve, reject) => {
    Upload.addListener('progress', uploadId, ({ progress }) => {
      console.log('[UPLOAD] progress', progress);
    });

    Upload.addListener('error', uploadId, ({ error }) => {
      console.log('[UPLOAD] error', { filePath, error });

      reject(error);
    });

    Upload.addListener('cancelled', uploadId, () => {
      console.log('[UPLOAD] cancelled', { filePath });

      const result = {
        isCanceled: true,
      };
      resolve(result);
    });

    Upload.addListener('completed', uploadId, async data => {
      console.log('[UPLOAD] completed', { filePath, data });

      const result = { success: true, data };
      resolve(result);
    });
  });

  return promise;
}

Same issue. But in the dev build it working fine, staging and production build facing the issue.
