Impossible to create a new parquet file?

[codegain]

Hi, after hours of trying I decided to open an issue here.

I'm trying to use this library to convert data from JSON -> parquet. This is my minimalized code:

import {ParquetSchema, ParquetWriter} from "@dsnp/parquetjs";

const schema = new ParquetSchema({
    some: {type: 'UTF8'},
    test: {type: 'UTF8'},
});

async function run() {
    const writer = await ParquetWriter.openFile(schema, 'test.parquet');
    await writer.appendRow({
        some: 'data',
        test: 'this'
    });

    await writer.close();
}

run();

I saved the file as test.ts and run it via npx tsx .\test.ts on my windows 11 machine with node v22.
It only gives me this output:

> npx tsx .\test.ts 

node_modules\thrift\lib\nodejs\lib\thrift\compact_protocol.js:553
    throw new Thrift.TProtocolException(Thrift.TProtocolExceptionType.INVALID_DATA, "Expected Int64 or Number, found: " + l);

  type: 1
}

The file test.parquet gets created, but it only creates the string PAR1 and nothing else.

Am I doing something wrong? Is the library not supposed to create new parquet files and only to append to existing ones? Or is this a bug?

To add to that: I get the same error when using the reference code in a test.js file and executing with node test.js:

import parquetjs from '@dsnp/parquetjs';

// declare a schema for the `fruits` table
var schema = new parquetjs.ParquetSchema({
    name: { type: 'UTF8' },
    quantity: { type: 'INT64' },
    price: { type: 'DOUBLE' },
    date: { type: 'TIMESTAMP_MILLIS' },
    in_stock: { type: 'BOOLEAN' },
});

// create new ParquetWriter that writes to 'fruits.parquet`
var writer = await parquetjs.ParquetWriter.openFile(schema, 'fruits.parquet');

// append a few rows to the file
await writer.appendRow({ name: 'apples', quantity: 10, price: 2.5, date: new Date(), in_stock: true });
await writer.appendRow({ name: 'oranges', quantity: 10, price: 2.5, date: new Date(), in_stock: true });

await writer.close();

    throw new Thrift.TProtocolException(Thrift.TProtocolExceptionType.INVALID_DATA, "Expected Int64 or Number, found: " + l);
          ^
TProtocolException: Expected Int64 or Number, found: 0

I found a quirky workaround: By downgrading from 1.8.7 to 1.8.3 the error is gone and everything is working (data is written to the parquet file).
