When calling macro "getDatasBibs", required parameter "node" (parameter #1) was specified, but had null/missing value.
----
Tip: If the parameter value expression on the caller side is known to be legally null/missing, you may want to specify a default value for it with the "!" operator, like paramValue!defaultValue.
