Error handling in Meteor.js with SimpleSchema

Question

I'm working a project developing by Meteor.js & now I'm working for a validation something like that

import SimpleSchema from 'simpl-schema';

const CompanySchema = new SimpleSchema({
    company_name: {
        type: String,
        min: 5,
        max: 50,
        label: "Company Name"
    }
});

Company.attachSchema(CompanySchema);

but in the console showing like below image

but when trying to keep the "Error" like this way

console.log(err.Error);

it's showing

undefined

here is insert functionalities

Company.insert(
    {
        company_name: inputs.companyName.value,
    },
    function(err) {
        if (err) {
            console.log(err);
        } else {
            console.log('Inserted successfully');
        }
    }
);

what's the issue actually.

Thanks

Could you please add the code of the method where the document gets inserted to the collection? — Jankapunkt, Mar 04 '19 at 12:33

I think it should be `err.message`. Also, you can validate an object before using it in the insert as shown [here](https://www.npmjs.com/package/simpl-schema#validating-an-object). — Sudheer Jami, Mar 05 '19 at 03:41

When your client-side Mongo insert fails it produces a native Error. If you log it's name, message and stack it shows the expected properties of an Error:

Company.insert(
    {
        company_name: inputs.companyName.value,
    },
    function(err) {
        if (err) {
            console.log(err.name);
            console.log(err.message);
            console.log(err.stack);
        }
    }
);

Produces:

Error 
Company Name must be at least 5 characters in company insert

The attribute err.error in contrast is part of the Meteor.Error, which is thrown if the insert fails inside a Meteor Method.

This would be the case for example in such code:

Meteor.call('someInserMethod', { company_name: 'abc' }, (err, res) => {
  console.log(err) // this error is a Meteor.Error
})
