Error trying to diff '[object Object]' in Angular

Question

Looks like something wrong with freight variable in HTML:

Error in app/freightList.component.html:13:8 Error trying to diff \'[object Object]\'

Answer 1

The problem (for me) was in my newState definition. Below is the correct definition:

const newState = (state, newData) => {
    return Object.assign([], state, newData);
}

My newState was converting my array to an object because I was using the wrong brackets - the Wrong Way is below.

const newState = (state, newData) => {
    return Object.assign({}, state, newData);
}

Good luck, I hope that helps, Rob
