Hi,
I'm trying to use queryJSON method of InfluxQLQueryApi.
If I have null values resulting from my query, the library fires an exception because of the cast forced to String.
As we can see from line 337 of the class:
JsonArray jvals = sobj.get("values").getAsJsonArray();
if (jvals != null) {
for(JsonElement jval : jvals) {
List<Object> values = new ArrayList();
JsonArray jae = jval.getAsJsonArray();
int index = 0;
for(JsonElement je : jae) {
List<String> columnKeys = new ArrayList(serie.getColumns().keySet());
if (this.extractor != null) {
String stringVal = je.getAsString();
Object ov = this.extractor.extractValue((String)columnKeys.get(index), stringVal, id, serie.getName());
values.add(ov);
} else {
values.add(je.getAsString());
}
++index;
}
Objects.requireNonNull(serie);
serie.addRecord(new InfluxQLQueryResult.Series.Record(serie, values.toArray()));
}
}
When it gets the null value, the instruction String stringVal = je.getAsString(); fires the exception.
Am I doing something wrong?
