[Pywps-dev] Raster Output error

Fri Jun 10 06:30:17 PDT 2016

Hi,

I'have changed from file to data in response.outputs['response'].data =
'done', but bow I still get an error in the response.

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 3.2 Final//EN">
<title>500 Internal Server Error</title>
<h1>Internal Server Error</h1>
<p>The server encountered an internal error and was unable to complete your
request.  Either the server is overloaded or there is an error in the
application.</p>

The GET request is written like this:

http://130.192.5.114:8080/wps?service=wps&version=1.0.0&request=execute&Identifier=rast_try&datainputs=raster=@xlink:href=file:///home/lorenzo/aspect_1ifGBx0

In the terminal I dont get any error report.

Tnx,

Lorenzo
