APIM not supporting multipart upload

Hi,

I am trying to upload bulk no. of files via APIM to Azure Blob storage. I used APIM Policies to upload the file with multipart/form-data. But it throwing me as unknow element error. How to upload multiple file to Azure blob with help of APIM.

Start by reproducing the multipart/form-data upload through an Azure API Management policy against Azure Blob Storage and capture the exact unknown-element error. Clarify whether multipart uploads are expected to be supported and, if so, define the affected policy entry point and a testable successful multi-file upload outcome.
