Dealing with FES 2014's all junk value

[maouyami]

Hello, I'm new to SCHISM and getting the FES 2014 data. This question might be a bit of a beginner's problem but...
I was trying the code on the online guide (https://schism-dev.github.io/schism/master/getting-started/pre-processing-with-pyschism/bctides.html), modifying it a bit for FES 2014 values.

import numpy as np

from pyschism.mesh import Hgrid
from pyschism.forcing.bctides import Bctides

if __name__ == '__main__':
    start_date = datetime(2017, 12, 1)
    rnday = 396
    bctypes = [[5, 5, 4, 4]]
    constituents = 'major'
    database = 'fes2014'
    earth_tidal_potential = True
    sthconst = [np.nan, np.nan, 0]
    tobc = [0.5, 0.5, 1]
    sobc = [0.5, 0.5, 1]
    outdir = './'
    hgrid = Hgrid.open("F:/Model/schism/hgrid.gr3", crs="epsg:4326")

    bctides = Bctides(
        hgrid = hgrid,
        flags = bctypes,
        constituents = constituents,
        database = database,
        add_earth_tidal = earth_tidal_potential,
        sthconst = sthconst,
        #tobc = tobc,
        #sobc = sobc,
    )

    bctides.write(
        outdir, 
        start_date=start_date, 
        rnday=rnday, 
        overwrite=True,
    )

Im sure i downloaded all of the FES 2014's data (eastward velocity, northward velocity, ocean tide extrapolated) from their ftp server. However when i run the code, it took an error

I assumed it was about FES 2014's velocity files. Any way to deal with this?
