Unable to upload files to data prep -An error occurred during upload

Talend version 6.2.1
Data prep was installed successfully, mongoDB is embedded. We are able to access the data prep portal. But while trying to upload a file, the UI says the following "An error occurred during upload"

app.log file shows the following error messages:
"2017-02-21 16:42:24.439 qtp840  ERROR o.t.d.e.TDPExceptionController
