I try to consume a web service within a new biztalk project. I clicked on “add generated items” and chose “Consume WCF Service” and MetaData files and XSD option but on last step i get the error:
“Error consuming WCF service metadata.Object reference not set to an instance of an object”.

I found target namespace is missing with <xsd schema=""> in wsdl and after adding i get the below error:

Error consuming WCF service metadata.Could not find a part of the path 'Message\Service References\service_camel_apache_org_cxf_jaxws_provider.xsd'

What I have tried:
