Symptoms
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.
RequestId:<ID>
MaxLimit : 4194304
Cause
This error can occur if the block size limit for the service version you run is exceeded. For example, versions prior to 2016-05-31 have a 4-MB block size limit per call to the Azure Storage service. Newer service versions support larger block sizes.

Workaround
If your file is too large, you must split it into chunks. For more information, see Scalability and performance targets for standard storage accounts.
