[BUG] GetPropertiesAsync fails in Firefox with TypeError: e.body is null

[hectorm-bmg]

Library name and version

Azure.Storage.Blobs, Version=12.22.2.0

Describe the bug

From a Blazor Client side project, when I call the following:

var props = await blobClient.GetPropertiesAsync();

Firefox fails with the following error:
TypeError: e.body is null

Other browsers work as expected and I can see the properties for my blob.

Expected behavior

The properties for the blob are returned to be use as needed.

Actual behavior

In Firefox, an exception is generated with the error message :

TypeError: e.body is null

Reproduction Steps

• Create a SAS write uri for a new blob
• Get a SAS url for the blob
• Use the following method to upload the new blob from a blazor client side app running in Firefox. You'll notice that the call to GetPropertiesAsync will fail as described above.

'
public async Task UploadStream(string blobName, Stream stream, Uri sasTokenUri, long totalSize)
{
var containerClient = new BlobContainerClient(sasTokenUri);

var blobClient = containerClient.GetBlockBlobClient(blobName);

var blockIds = new List<string>();

var buffer = new byte[MaxChunkSize];
int bytesRead;
int blockNumber = 0;

var totalChunks = (totalSize / MaxChunkSize) + 1;

while ((bytesRead = await stream.ReadAsync(buffer, 0, buffer.Length)) > 0)
{
    Logger.LogInformation($"Uploading block {blockNumber}/{totalChunks} for {blobName}.");

    string blockId = Convert.ToBase64String(Encoding.UTF8.GetBytes($"{blockNumber:D6}"));
    blockIds.Add(blockId);

    // Upload the block
    using var chunkStream = new MemoryStream(buffer, 0, bytesRead);
    await blobClient.StageBlockAsync(blockId, chunkStream);

    blockNumber++;
}

// Commit the blocks
await blobClient.CommitBlockListAsync(blockIds);

var props = await blobClient.GetPropertiesAsync();

while (props != null && props.Value.ContentLength < totalSize)
{
    // Check that the file has finished uploading.
    await Task.Delay(5000);
    Console.WriteLine($"Waiting for blob {blobName} to finish uploading.");
    props = await blobClient.GetPropertiesAsync();
}

}
