Scratch my last response. The file does not appear with the “path/” prefix in the s3 bucket. The issue is that there does not seem to be a way to pass in a path OR to manipulate the filename when passing back to the upload provider. The path is always listed as null when it arrives to the upload function on the backend and any attempt to change the entityFile.name property is met with an error:
TypeError: Cannot set property name of #< File > which has only a getter
note that the third property in this line is not used and the filename is ultimately sourced from the ‘name’ property itself on the file entity
formData.append(files.fileAttachment,entityFile,entityFile.name);
