Problem with snappy.ProductIO.writeProduct()

snap
#1

I am using snap to process sentinel-1 datasets.

Everything works well until I try to save the processed data to file. Please see my code and the error generated below.

Code

    import snappy as sp
    import SAR_Processing_Functions as spf

    fp = 'path to file'
    data = sp.ProductIO.readProduct(fp)
    data = spf.Apply_Orbit(data)
    data = spf.Multilook(data)
    data = spf.Calibration(data)
    data = spf.Speckle_Filter(data)
    data = spf.Terrain_Correction(data)
    sp.ProductIO.writeProduct(data, './trial', "GeoTIFF")

Error :
