I am attempting a PnR in connection with the Transition of Care workflow. However, the response from the HISP includes a RegistryErrorList with a NullPointerException:
<ns3:RegistryResponse xmlns="urn:ihe:iti:xds-b:2007" xmlns:ns2="urn:oasis:names:tc:ebxml-regrep:xsd:rim:3.0" xmlns:ns3="urn:oasis:names:tc:ebxml-regrep:xsd:rs:3.0" xmlns:ns4="urn:oasis:names:tc:ebxml-regrep:xsd:query:3.0" xmlns:ns5="urn:oasis:names:tc:ebxml-regrep:xsd:lcm:3.0" status="urn:oasis:names:tc:ebxml-regrep:ResponseStatusType:Failure"><ns3:RegistryErrorList highestSeverity="java.lang.NullPointerException"><ns3:RegistryError codeContext="java.lang.NullPointerException" errorCode="java.lang.NullPointerException" location="XDR.java" severity="Error">java.lang.NullPointerException</ns3:RegistryError></ns3:RegistryErrorList></ns3:RegistryResponse>
What causes this?
