WCS processing wcs2:get-proc-req15-17 failed with Parser {http://www.occamlab.com/te/parsers}HTTPParser threw an exception

[bangph]

I use this endpoint http://conformance.rasdaman.com/rasdaman/ows?service=WCS&version=2.0.1&request=GetCapabilities to test WCS WCPS 2.0 (Processing).

It failed in reqd15-17 with strange error in teamengine:

Log for test s0110/d13242e81_1/d18145e136_1

Test wcs2:get-proc-req15-17 type Mandatory default result Passed (s0110/d13242e81_1/d18145e136_1)

Assertion: Req15-17:Send valid ProcessCoverages requests using the WCS SOAP protocol. Check that the result is correct.

Error in call to extension function {public org.w3c.dom.NodeList com.occamlab.te.TECore.soap_request(org.w3c.dom.Document,java.lang.String) throws java.lang.Throwable}: 
Exception in extension function java.lang.RuntimeException: 
Parser {http://www.occamlab.com/te/parsers}HTTPParser threw an exception.
Result: Failed

I tried to understand what it tested, here it just sends a WCPS query which encode in PNG.

@dstenger can you please give some ideas with that? The java exception is not useful for me to know what is wrong.

[dstenger]

Thank you for reporting. We will do further investigation.

[dstenger]

The error can also be reproduced on a local environment.

Following StackTrace is logged: log.txt

[dstenger]

It seems that following request body returns an image (extracted from the test).

<proc:ProcessCoverages 
    xmlns:wcs="http://www.opengis.net/wcs/2.0"
    xmlns:gml="http://www.opengis.net/gml/3.2"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xmlns:proc="http://www.opengis.net/wcs_service-extension_processing/2.0"
     service="WCS"  version="2.0.1">
    <proc:query>
        for c in ( <xsl:value-of select="$CoverageId"/> )
        return  encode (c, "png")
        </proc:query>
</proc:ProcessCoverages>

However, the test expects XML.

@bpross-52n Can you please do further investigation?

[bangph]

@dstenger thanks for your quick investigation. I'm not sure if the test suite for WCS Processing has changed recently or not. I hope @bpross-52n can have some ideas soon.

[dstenger]

No, this code has not been changed for a long time (last commit is from 2015). Can you recall if you were able to pass this test in the past?

[bangph]

@dstenger yes, last year I ran it for renewing OGC CITE certificates without problem. Not sure what is wrong here.

[bangph]

@dstenger FYI: I'm using a new software version on http://conformance.rasdaman.com/rasdaman/ows?service=WCS&version=2.0.1&request=GetCapabilities. I can check an older version of it which passed this requirements last years as well. It may give some ideas.

[bangph]

@dstenger I think the reason is, this req15-17 needs to have SOAP body to wrap the binary content. That doesn't exist in our new software and I will fix that.

SOAP:

I will close this ticket.
