We have

Attribute.DataType (i=17) or Value (Value: Null, StatusCode: Good (0x00000000), SourceTimestamp: 2018-11-14T15:20:06.523Z,
ServerTimestamp: 2018-11-14T15:20:06.523Z, of current Instance (i=13631) doesn't match the expectation (BuiltInType.NodeId)

Object Server,ServerConfiguration,CertificateGroups,DefaultApplicationGroup is not compliant with the UA 1.03 NodeSetFile.

The DefaultApplicationGroup has a property of type CertificateTypes i=13631
which is of DataType="NodeId" ValueRank="1".

The scrript Fails because of the missin NodeId entry here:

With this patch the Problem disappears.
