NetCDF data cannot be saved by the GeoServer raster data source

Question

My NetCDF file (ERA5 data) is based on CF convention, with 1-dimensional coordinates.

After browsing the NetCDF file, it cannot be saved by the data source, showing the error below:

 There was an error trying to connect to store netcdf_file. Do you want to save it anyway?

Original exception error:

GeoServer Error image

GeoServer Version is 2.22, and the GeoServer NetCDF plugin has been installed successfully.

At first, the NetCDF had 4 dimensions (time, level, lat, lon). I changed it to 3-dimention (time, lat, lon). But the problem was not solved.

Answer 1

I have no issues publishing the file in GeoServer, e.g:

and the d2m variable:

It may be you are storing the NetCDF in a directory where GeoServer cannot add its index files, normally included as hidden sidecar directories. The GeoServer NetCDF guide guide has a section about this case.

Answer 2

It is interesting that GeoServer 2.23.0 is okay with storing and publishing NetCDF (ERA5 data). I think I just replaced GeoServer 2.22 with 2.23 and added the NetCDF plugin, and also changing to Java 11.

Published NetCDF (another data) for the variable d2m
