uploaded files sometimes get truncated

### Which service(blob, file, queue) does this issue concern?
Blob storage

### Which version of the SDK was used? Please provide the output of `pip freeze`.
azure-storage==0.34.3
azure-storage-blob==1.5.0
azure-storage-common==1.4.0
azure-storage-file==1.4.0
azure-storage-nspkg==3.0.0
azure-storage-queue==1.4.0

### What problem was encountered?
When uploading a json file with `BlockBlobService().create_blob_from_path`, sometimes the file gets truncated. This happens both when a file with the same name already exists in the blob storage and when it does not. It does not happen with all json files. I have one json file that contains the full dataset, for which upload does not give any issues. If I upload a json file with only a subset of the data, the file gets truncated. Both files were created in the same way.
Truncation happens during upload, the local version I have of the files are perfectly fine. Unfortunately I cannot share the files in question.
Uploading the file through the portal does not give any issues, so I suspect it has nothing to do with the file itself.
The issue is very similar to this one: https://github.com/Azure/azure-storage-azcopy/issues/207

### Have you found a mitigation/solution?
I manually upload the files through the portal, but this solution is not tenable.

Note: for table service, please post the issue here instead: https://github.com/Azure/azure-cosmosdb-python.

Bắt đầu tại BlockBlobService().create_blob_from_path và tái hiện việc upload với hai trường hợp tệp JSON được mô tả trong issue, đồng thời so sánh nội dung cục bộ và nội dung đã upload. Hoàn tất nghĩa là xác định được lý do một số lần upload bị cắt ngắn và xác nhận rằng các tệp bị ảnh hưởng được upload nguyên vẹn; issue không cung cấp test hoặc tệp nguồn cụ thể nào.

Do mô hình lập chỉ mục viết ra từ nội dung của issue.
