I have read the document  Dynamic colormap generation
<https://docs.geoserver.org/stable/en/user/community/colormap/index.html>  ,
but I still can not display my layer with dynamic colormap.

What I did:
1. use command "gdalinfo -stats my.nc" to create the PAM Auxiliary
file(.aux.xml)
2. Add my netcdf file as data store and publish it( I hava installed the
netcdf extension)
3. create a file named "indexer.properties" with the content
"CheckAuxiliaryMetadata=true", the properties file is beside my netcdf file
4. install the dynamic colormap community extension(2.14-SNAPSHOT-colormap)
4. add a new dynamic style according to the document

What I got:
When I preview the layer, an exception is thrown, showing "Filter Function
problem for function gridCoverageStats: Unable to find the stat minimum from
the input object of type class"

Addition info:
My GeoServer version is 2.14

Could you give me some suggestion?
Thanks in advance

Rayman
