AttributeError "cannot write attribute with reserved name '_NCProperties' " when using make_local

When using cate python api for some datasets the following error occurs: AttributeError "cannot write attribute with reserved name '_NCProperties' "

This happens for some datasets which have not problem when opening from remote. this happens e.g. for

esacci.SST.satellite-orbit-frequency.L3U.SSTskin.AVHRR-3.Metop-A.AVHRRMTA_G.2-1.r1 time range ('2006-11-21', '2006-11-23') region "-49.8, 13.1,-49.7, 13.2" variables ['sst_dtime', 'sea_surface_temperature_depth']

Expected behavior

I would expect no error occurring, as the dataset collection does not fail when opening from remote.

EDIT: This issue occurs when executing

data_source = data_store.query('esacci.SST.satellite-orbit-frequency.L3U.SSTskin.AVHRR-3.Metop-A.AVHRRMTA_G.2-1.r1')[0]
ds_from_local = data_source.make_local('local_ds_sst', time_range=('2006-11-21', '2006-11-23'), var_names=['sst_dtime', 'sea_surface_temperature_depth'], region='-49.8, 13.1,-49.7, 13.2' )
