AbdelouahabKhelifati opened a new issue #12372:
URL: https://github.com/apache/druid/issues/12372
Please provide a detailed title (e.g. "Broker crashes when using TopN query
with Bound filter" instead of just "Broker crashes").
### Affected Version
Druid 0.22.0
### Description
I am running Druid with the following conf:
```
druid.service=druid/broker
druid.plaintextPort=8082
# HTTP server settings
druid.server.http.numThreads=60
druid.server.http.maxSubqueryRows = 100000000
# HTTP client settings
druid.broker.http.numConnections=50
druid.broker.http.maxQueuedBytes=10MiB
# Processing threads and buffers
druid.processing.buffer.sizeBytes=500MiB
druid.processing.numMergeBuffers=16
druid.processing.numThreads=1
druid.processing.tmpDir=var/druid/processing
# Query cache disabled -- push down caching and merging instead
druid.broker.cache.useCache=false
druid.broker.cache.populateCache=false
druid.extensions.loadList=["druid-stats"]
```
Then, I try to run a simple Standard Deviation query as follows:
```
select STDDEV("value")
from mytable
```
However, I keep having the following error:
```
Error: Unknown exception
Could not resolve type id 'variance' as a subtype of
`org.apache.druid.query.aggregation.AggregatorFactory`: known type ids =

-1, column: 1242] (through reference chain:
org.apache.druid.query.timeseries.TimeseriesQuery["aggregations"]->java.util.ArrayList[0])
com.fasterxml.jackson.databind.exc.InvalidTypeIdException
```
I am using Druid version 0.22.0.
How could this be solved?
Thanks!
