I may also had a problem with the same root cause. In my case it was a formating error and a special charakter in the Textfile that was uploaded.
Try this to identify the line that cause the error:
Every app in QRadar has its own logs.
SSH to the QRadar

Run
/opt/qradar/support/recon ps
to get a list of the installed apps, take note of the four-digit ID number of the app you're

Run
/opt/qradar/support/recon connect <1251=example ID>

Run cat/grep/... on
/store/log/app.log
to see the logs of the app
When you're done, just type
exit

Means a special charakter is used. In the example below it was an "ü"
An invalid parameter was passed to the API call; error message: {u'details': {}, u'message':
u"Problem with entry {name: 'Reserviert_f\xfcr_interne_
the word in the textfile was: "Reserviert_für_interne_"
