Some errors thrown as exceptions rather than being passed to parseXlsx's callback

[addrummond]

Unfortunately I'm not familiar enough with the promise library to be able to see how to fix this yet, but it seems that some errors get thrown as exceptions rather than being passed to the callback given to parseXlsx. For example, if you give parseXslx the path of a nonexistent file, an ENOENT exception is thrown. The intended behavior is (presumably?) for such errors to be passed on to the callback.

var parseXlsx = require('excel');

parseXlsx('nonexistent-file', function () {
    console.log(arguments);
});

======> Throws exception

I was trying this

My app.js

var express = require('express'); //Call Express module
var app = express(); //Create server
var parseXlsx = require('excel');

    parseXlsx('Sheet.xlsx', function(err, data) {
        console.log('sdf');
        if(err) throw err;
        // data is an array of arrays
        console.log(data);
    });

app.listen(3003);

But I'm getting error

/home/local/user/Desktop/sample/node_modules/excel/node_modules/node-promise/promise.js:199

      throw error;
            ^

How to fix this issue? My file is existing i crosschecked it. My xlsx file is in the same folder as app.js

It's the issue with the old 'unzip' library version used - it doesn't support zip format used by LibreOffice and Google Docs for producing XLSX

[kbanman]

I'm running into this error as well. Would it be possible to get around this by using a different unzip library?

[amakhrov]

I believe a new unzip lib is used already - could you confirm you use the most recent versions of excel module? If yes, could you post the error output here?

I am able to build and install on the same development board using 3.1.2 I've sent a bug ticket to BCM.
