NCL 6.3.0 is the current version, and that includes many updates to the GRIB tables that would possibly take care of the errors you see. It appears you are trying to read a relatively recent ECMWF file, which likely has some variables that were added to the model output at some point in the last two years. The good news is that, unless you are trying to use those more recently defined variables, your file has likely converted successfully.</p>
<p dir="ltr">Please update your NCL version, if you are able, and let the list know if you still have problems after that.<br></p>
