RangeError: Invalid typed array length

[trong]

Построение словаря:

from pprint import pprint
import dawg

words = [ u'ABC', u'ABCD', u'ABCS', u'АБВ', u'АБВГ', u'АБВЦ' ]
d = dawg.CompletionDAWG(words)
d.save('../data/words.dawg')

print(d.keys("ABC"))
print(d.keys("АБ"))

# Output: 
#   ['ABC', 'ABCD', 'ABCS']
#   ['АБВ', 'АБВГ', 'АБВЦ']

Готовый словарь: words.dawg.zip

Инициализация словая в JS:

import {readStringMapDawgSync} from "dawgjs";

let dawg = readStringMapDawgSync('../../data/words.dawg', bytes => {
    let view = new DataView(bytes.buffer);
    return {
        paradigmId: view.getUint16(0, true),
        indexInParadigm: view.getUint8(2)
    };
});
console.log(dawg.get("АБВ"));
