Description

I'm trying to create load an arrow file in IPC format. 

First, I load the library

import

{ Table }

from "@apache-arrow/es2015-esm";

Then, I fetch the file and convert it to the buffer (it would be nice if this wasn't necessary)

fetch(require("../data/flights-10k.arrow")).then(response => {
response.blob().then(blob => {
let arrayBuffer;
const fileReader = new FileReader();
fileReader.onload = function()

{ arrayBuffer = this.result; const table = Table.from(arrayBuffer); console.log(table.toString()); }

;
fileReader.readAsArrayBuffer(blob);
});
});

Now I get the error "Uncaught TypeError: Cannot read property 'fields' of undefined"
