Weird overlappingsync issue

[kylebernhardy]

LMDB.js 2.3.8 Ubuntu 20.04

I am running into issues in my tests when interacting with empty environments. This code throws an error:

'use strict';

const lmdb = require('lmdb');
const fs = require("fs");

(async()=> {
    try {
        fs.rmSync('./data', {recursive: true});
    }catch (e) {};
    let env_init = {
        "path": './data',
        overlappingSync: true
    };
    let env = lmdb.open(env_init);
    let dbi = env.openDB('test', {
        dupSort: false,
        sharedStructuresKey: Symbol.for('structures')
    });
    await env.close();
})()

Error:

/home/kyle/code/lmdb-test/node_modules/lmdb/dist/index.cjs:482
                                        env.sync(() => {
                                            ^

Setting overlappingsync to false does not thro an error:

'use strict';

const lmdb = require('lmdb');
const fs = require("fs");

(async()=> {
    try {
        fs.rmSync('./data', {recursive: true});
    }catch (e) {};
    let env_init = {
        "path": './data',
        overlappingSync: false
    };
    let env = lmdb.open(env_init);
    let dbi = env.openDB('test', {
        dupSort: false,
        sharedStructuresKey: Symbol.for('structures')
    });
    await env.close();
})()
