The uploading of input units is an asynchronous process.
Our API performs a variety of syntax evaluations upon method invocation and will return syntax-type errors
immediately.
If the uploaded input units passes syntax evaluations, the Project state will change to PROCESSING DATA UPLOAD.
Errors found during asynchronous processing of the uploaded input units will change the Project state to UPLOAD
ERRORS.
To retrieve the specific errors for each input unit call Get Project Status.
