Method error when running high.jl

[petershintech]

When I running high.jl line by line, I got the following error.

julia> nccreate(fn1,"vchar","DimChar",20,"Dim2",t=NetCDF.NC_CHAR)
20×10 NcVar{NetCDF.ASCIIChar,2,2}:
Error showing value of type NcVar{NetCDF.ASCIIChar,2,2}:
ERROR: MethodError: no method matching nc_get_var1_x(::NcVar{NetCDF.ASCIIChar,2,2}, ::Array{UInt64,1}, ::Type{NetCDF.ASCIIChar})
Closest candidates are:
