Hi,
It looks like a problem with your meteorological HDF file:
HDF5-DIAG: Error detected in HDF5 (1.10.0-patch1) thread 140522629941056:
#000: H5T.c line 1712 in H5Tcopy(): not a datatype or dataset
Did it download properly? Maybe the AOI was too small, have a look at Error Preparing ERA 5 reanalysis data (Sen-ET plugin)
