Property '_body' does not exist on type 'Response'

Question

I am using Angular 2 and getting this error when using an observable Property '_body' does not exist on type 'Response'. The code is below

this.securitiesService.getMarketMovers()
    .subscribe(data => {
        console.log(JSON.parse(data._body))
    });

The getMarketMovers function is simply this:

getMarketMovers() {
    return this._http.get('...url address...')
}

I have tried to set data to type any but that isn't working for me. The code works and there is definitely a _body property on data but it still throws there error and I cant build with this error.

Any help is greatly appreciated.

You getting an run-time error or compile-time error? Sounds for me like an compile-time error, so you have to cast that `data` variable to your correct type. Or your `getMarketMovers` function should be return the correct type! — slaesh, Sep 19 '16 at 13:41
Thanks! I put `:any` after my getMarketMovers function `getMarketMovers(): any` and it works — georgej, Sep 19 '16 at 14:44

UPDATE

Another way, is to explicitly tell TypeScript that we’re not interested in doing strict type checking.

(<any>data)._body

ORIGINAL

This data["_body"] should work.

this looks like a hack IMHO, is there better way to check if a Response has empty body? – Toolkit Dec 12 '16 at 13:10
This is the only way I could make it work, thank you! :) – balazs630 Oct 18 '17 at 15:16
Wow, for anyone looking to fix problems like not being able to access properties coming back from a call, this is your answer! confounded typescript! i read all kinds of stuff like this, but its just Typescript! https://stackoverflow.com/questions/17546953/cant-access-object-property-even-though-it-exists-returns-undefined – russiansummer Nov 02 '17 at 19:20

I went for the original because it seems way cleaner. Thank you. – Joe Eifert Dec 14 '18 at 11:15

You can also use `(data as any)._body` incase you have a [forbidden angle bracket assertion](https://palantir.github.io/tslint/rules/no-angle-bracket-type-assertion/) – Dylan T. Jun 29 '20 at 20:20

data.json();

will give you the json result: https://angular.io/docs/ts/latest/guide/server-communication.html

to solve this error better way would be to add. : Promise <any> after getMarketMovers() function.
