Reported problem in fileout_netcdf associated with _FillValue in Ocean Color dataset

Description

A user reports that trying to get the netcdf fileout response for this dataset:

https://oceandata.sci.gsfc.nasa.gov/opendap/MODISA/L3SMI/2018/285/A2018285.L3m_DAY_SST_sst_4km.nc

Returns an "empty" 165 byte file.

After checking into this we see that the return is a DAP2 error:

Looking at the:


I suspect that the _FillValue for the Byte variable qual_sst was probably being mishandled (as in converted to a signed value or some such). Certainly asking for just qual_sst produces the error:

The server is run-in Hyrax 1.12.1 so this issue may be fixed in the current release but we must check.

Lacking the source data file we can build a test dataset using ncgen with a variable that mimics qual_sst and test against that. same properties

I was never able to get a response from the admins at oceandata.sci.gsfc.nasa.gov. I made that attached test dataset and the current code base has no problem producing fileout_nectdf representations of it. So… I am closing this as a No-OP
