Currently, this API function returns the status of a currently running upload.
So, when I submitted an upload and then ran this function, results actual upload status was returned.
After the upload finishes the completed status seems to be unavailable - see below 'Response'.
The current description shows: "
CheckIfLastUploadCompletedSuccessfully Check If last upload completed successfully", which I find unclear.
I plan to check and correct the description or see if the function needs to allow detection, even after an upload finishes.
However, currently, this API function only returns the status of a currently running upload.
