Unable to upload to blob storage, missing Access-Control-Allow-Origin header
问题 Using the @azure/storage-blob module in the browser, it's not possible to upload to azure storage directly. It complains about a missing request header. The upload is done from within a ReactJS app running as an Office Add-in. As required by Microsoft, CORS have been enabled on storage account for blobs. I tried finding a way to add custom HTTP Headers however, none worked. Here's the upload code import { Credential, BlobServiceClient} from "@azure/storage-blob/browser/azure-storage-blob.min
