bonares csw returns 'Document is XML, but not CSW-ish'

[pvgenuchten]

when using below url as csw service

https://maps.bonares.de/soapServices/CSWStartup

from owslib.csw import CatalogueServiceWeb
csw = CatalogueServiceWeb('https://maps.bonares.de/soapServices/CSWStartup')
csw.getdomain('GetRecords.resultType')

we get error:

Document is XML, but not CSW-ish

The software behind this endpoint is smart finder based on arcgis server stack

The issue came up when i was trying to connect qgis metasearch to this endpoint, but then realised that the warning is coming from owslib
