Describe the bug I understand this may not be related to @azure/storage-blob per se (as it look tracing related), but as the issue is triggered by a call to a code similar to the following one, I’ve figured this repo maight be a good starting point.

    const bc = new BlobClient(connectionString, containerName, blobPath, undefined);

    const downloadBlockBlobResponse = await bc.download(undefined, undefined, { conditions: { ifNoneMatch: lastKnownEtag } });

    // From https://github.com/Azure/azure-sdk-for-js/blob/af9572946ce1ba33c89118f21dd3809dbb241732/sdk/storage/storage-file-share/src/utils/utils.node.ts
    // Licence MIT (https://github.com/Azure/azure-sdk-for-js/blob/master/LICENSE)
    const buf = await streamToBuffer3(downloadBlockBlobResponse.readableStreamBody!);

After having implemented the outcome of #13481, we’re now hitting the following exception.

To Reproduce I haven’t been able to create a standalone repro yet from scratch which would recreate the issue. And it may take me a little time before being able to make one emerge by through the removal of unnecessary production code. So I’ve figured I’d create this here in the meantime.
