This is how I did:
- I have a Create Form Task Activity, where I have configured the storage bucket and I have a form control for uploading files
uploadedContract - is the field key for the File form control
- On a Wait for Form Task and Resume Activity for Task Object (Output) I have set a property: taskObjectFormResumed
Then to know if a new file was added I have: JObject.Parse(taskObjectFormResumed.Data.ToString())(“uploadedContract”).First(“filePath”).ToString() , which is indicating me the file name from Storage Bucket
