我正在尝试以下SPARQL查询:

SELECT ?uri ?label
WHERE {
    ?uri rdfs:label "Weblex"@en .
    ?uri rdfs:label ?label
}

但是,我收到一条神秘的错误消息:

ERROR: SPARQL-QUERY: queryStr=SELECT ?uri ?label
WHERE {
    ?uri rdfs:label "Weblex"@en .
    ?uri rdfs:label ?label
}
java.util.concurrent.ExecutionException: 
java.util.concurrent.ExecutionException: java.lang.RuntimeException: 
java.util.concurrent.ExecutionException: 
java.lang.IllegalArgumentException: Unable to read data: 
com.bigdata.rwstore.PhysicalAddressResolutionException: Address did not resolve to physical address: -118579
at java.util.concurrent.FutureTask.report(FutureTask.java:122)

查询看起来像是有效的,所以我在做什么错了?
