The following SMS mapping works fine ..

MAPPING  
FROM CSV { }  
TO {  
?source\_iri a :Xxx .  
?source\_iri :description ?desc ;  
:name ?source\_name ;  
... }  
WHERE {  
BIND(TEMPLATE("[https://example.com/{source}](https://example.com/%7Bsource%7D)") AS ?source\_iri)  
BIND(StrDt(sourceField("description"), xsd:string) AS ?desc)  
BIND(StrDt(sourceField("name"), xsd:string) AS ?source\_name)  
... }

But, if I change the variable, source\_name, to name .... I get an import error:

Error importing file '/Users/andreaw/Downloads/source-details.csv'. Server Error (java.lang.NullPointerException), check logs for details

The log entry is very vague, failing at:  
com.google.common.base.Preconditions.checkNotNull(Preconditions.java:889) ~[guava-31.1-jre.jar:?]
