I'm new in GIS and i'm starting to use pywps. I write THIS process but doesn't work. It returns this:

Traceback (most recent call last): File "/usr/local/lib/python2.7/dist-packages/pywps-3.2.2-py2.7.egg/pywps/Wps/Execute/init.py",
line 387, in init self.consolidateInputs()
File "/usr/local/lib/python2.7/dist-packages/pywps-3.2.2-py2.7.egg/pywps/Wps/Execute/init.py",
line 547, in consolidateInputs
raise pywps.MissingParameterValue(identifier)
MissingParameterValue: < ?xml version="1.0" encoding="utf-8"?>
< ExceptionReport version="1.0.0" xmlns="http://www.opengis.net/ows/1.1" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.opengis.net/ows/1.1 http://schemas.opengis.net/ows/1.1.0/owsExceptionReport.xsd">
< Exception exceptionCode="MissingParameterValue" locator="text"/>

How can i fix this?

  • Hi, have you tested also the GetCapabilities and DescribeProcess request? – doktoreas Nov 24 '14 at 22:05
  • Yes, I tested and it seems alright... – MarcoPSM Nov 25 '14 at 11:00
  • Can you post the Execute request? It seems that you are not providing the "text" parameter. – doktoreas Nov 25 '14 at 14:32
  • request: http:// localhost/cgi-bin/pywps.cgi?VERSION=1.0.0&REQUEST=Execute&SERVICE=WPS&IDENTIFIER=firstprocess – MarcoPSM Nov 25 '14 at 16:22

You are missing the datainputs. Take a look here for an example using KVP request. You can also test the WPS service using the QGIS WPS plugin.

  • added the following &DataInputs=[text1=Marco] and it worked thanks! – MarcoPSM Nov 25 '14 at 19:19
