Hello I'm relatively new to the cloud foundry and AWS. I'm creating a UI with SAPUI5 for the Retraining of Customizable Services on Cloud Foundry (https://help.sap.com/viewer/a86b12f81f424c45a0e7c83c1d5025c4/1904A/en-US/65df4d78cb6b485aab2c9fb11ae89ac1.html) and I'm stuck on uploading the dataset. There are many tutorials on how to do it using the command line interface, but I can't find anything on how to upload a filesystem using HTTP requests. While every other step can be done using the API for this service, I don't understand how the HTTP request is supposed to be implemented when communicating with the AWS.
