Error: Uncaught (in promise): RestError: Failed to send request

See original GitHub issue

PackageName: @azure/storage-blob Version : 12.2.1 Node: v14.4.0 OS : Windows

Here is my code for upload files to Blob:

 public uploadFilesToAzureBlob(sasToken: string, file: any, id: string): Observable<any> {
    const blobServiceClient = new BlobServiceClient(sasToken);
    const containerClient = blobServiceClient.getContainerClient(id);

    if (!containerClient.exists()) {
      containerClient.create();
    }

    const client = containerClient.getBlockBlobClient(file.name);

    // 10MB block size and 20 concurrency
    const response = client.uploadBrowserData(file, {
      blockSize: 10485760,
      concurrency: 20,
      blobHTTPHeaders: {
        blobContentType: file.type
      }
    });

    return from(response)
      .pipe(map((res: any) => res),
        catchError(this.handleError));   }

Getting below errors after 5-10 seconds of uploading the files, though file/s is/are successfully uploaded…

Any suggestion?

Hi, these errors are from network layer, usually caused by network spike. Please double check uploaded data integrity, although blob is created. Recommend to increase max retry count in client options if you want to deal with some bad network situations.
