I'm not able to reproduce this error. In general, the capabilities document seems invalid. Have you tried validating it?

[dstenger]

@keshav-nangare Can you please recheck the reported error? Can you also add what environment you used for testing?

[keshavnangare]

This issue is reproducible on local as well as on beta environment, according to the error log I think the service is invalid.

Locally tested on: OS: Windows 8.1 Teamengine: 5.2 ets-csw20 : 1.17

[dstenger]

We should check if the error message can be improved.

Well, I can reproduce the failure too. Test csw:csw-2.0.2-GetRecordById-tc1.2 fails with the failure above. The following request (https://gptogc.esri.com/geoportal/csw)

<csw:GetRecords xmlns="http://www.occamlab.com/ctl"
                xmlns:csw="http://www.opengis.net/cat/csw/2.0.2"

                xmlns:xs="http://www.w3.org/2001/XMLSchema"
                xmlns:xsd="http://www.w3.org/2001/XMLSchema"
                resultType="results"
                service="CSW"
                version="2.0.2">
   <csw:Query typeNames="csw:Record">
      <csw:ElementSetName>brief</csw:ElementSetName>
   </csw:Query>
</csw:GetRecords>

returns a GetRecords response with multiple BriefRecords and dc:identifier. E.g.:

<csw:BriefRecord>
         <dc:identifier scheme="urn:x-esri:specification:ServiceType:ArcIMS:Metadata:FileID">http://www.tnccmaps.org:80/arcgis/services/GDE/pGDEs_FoxCanyonwebmap_GDEs/MapServer/1</dc:identifier>
         <dc:identifier scheme="urn:x-esri:specification:ServiceType:ArcIMS:Metadata:DocID">{631CD53C-ABCB-4A03-AB89-8248F2B12A5B}</dc:identifier>

Test test does not consider multiple occurrences of dc:identifier, it selects all: https://github.com/opengeospatial/ets-csw202/blob/4bd0a94d1bc40def874c79e665e5775170128e6f/src/main/scripts/ctl/GetRecordById/CSW-GetRecordById-GET.xml#L159

This should be fixed to select the first one and rechecked if the failure occurs any longer.
