Hi,
the problem, the HTTP 400 error is probably caused by values in your query params...following parameters and values caught my attention:
- FileName=1
- FileContents=1
- TimeStamp=1
Try to send correct values and check if it's working.
In my opinion, this isn't a SoapUI problem/bug.
The problem is probably in the TimeStamp parameter, because you're sending incorrect value (and format) and your code can't processed it correctly and therefore it's returning that error.
Try to send values which are specified in the curl command.
And btw, is that curl command working for you?
Regards,
Marek
