Error when you write more than 4 MB of data to Azure Storage: Request body is too large
Original product version: Storage Account Management
Original KB number: 4016806
Assume that you try to write more than 4 megabytes (MB) of data to a file on Azure Storage, or you try to upload a file that's larger than 4 MB by using the SAS url (REST API) or HTTPS PUT method. In this scenario, the following error is returned:
Code : RequestBodyTooLarge
Message: The request body is too large and exceeds the maximum permissible limit.
MaxLimit : 4194304
There's a 4-MB limit for each call to the Azure Storage service. If your file is larger than 4 MB, you must break it in chunks. For more information, see Azure Storage scalability and performance targets.
