Webpack: Cannot read properties of undefined (reading 'stat')

[stefanonardo]

Steps to reproduce

webpack === 5.72.1 typescript === 5.3.3 @dsnp/parquetjs == 1.6.2 node === 20

craco.config.js

webpack: {
    configure: (webpackConfig) => {
      webpackConfig.resolve = {
        ...webpackConfig.resolve,
        alias: {
          '@dsnp/parquetjs': path.resolve(__dirname, 'src', 'parquetjs', 'dist', 'browser', 'parquet.cjs.js'),
        },
        fallback: {
          crypto: require.resolve('crypto-browserify'),
          stream: require.resolve('stream-browserify'),
        },
      };

      return webpackConfig;
    },
  },

app.js

import * as pq from '@dsnp/parquetjs';

const reader = await pq.ParquetReader.openFile(file.name);

Expected behaviour

it reads the file

Actual behaviour

throws error

Any logs, error output, etc?

@stefanonardo Are you running this in a browser or in Node?

• If a browser, what is your file.name value?
• If in Node, why are you using the browser version

[stefanonardo]

hey @wilwade, thank you for answering. I moved to another library so I cannot test it anymore, you can close the issue. However, I was running it in a browser andfile.name was a string containing the name of an uploaded file (through Antd Upload component).

Thanks for the update!
