Error trying to diff '[object Object]' in Angular
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
I ran into this issue when I changed the WebApi I was calling to return a Task<IActionResult> instead of the previous IEnumerable<object>. Check the response isn't wrapped in an object. I had to change my extractData method to:
private extractData(res: Response) { let body = res.json(); return body.result || body || { };}
