Out of order elements causes error

[ChrisAlvares]

Having elements outside of the normal adwords order causes issues with the sdk / api.

Test Case

//this will work
let operation = {
    operator: 'ADD',
    operand: {
     ....
    }
}

//this will not work
let operation = {
    operand: {
     ....
    },
    operator: 'ADD',
}

We might need to read the wsdl to determine the order of elements or something. Not really sure how to solve this one as dynamically as possible.

For now, having the elements in the correct order is the workaround.

Yes this is an issue with XML soap requests, order needs to be preserved. I implemented this by reading the WSDL. It's done in my fork of the googleads-node-lib, adwords-api.

I really like the simplicity of this package though and thinking about deprecating that package as it's just too much mess with Backbone models etc.

I think mentioning that order needs to be preserved in readme, is good enough for now.

I will put it in the readme, but I think reading the wsdl might be a good thing. Perhaps even caching it in the package like we do here: https://github.com/ChrisAlvares/node-adwords/blob/master/services.js

You don't necessarily need to read the WSDL as the documentation has everything in the correct order as well.
