Angular/TypeScript typing of JSON response

I have a function in my Angular app that calls a backend server:

requestLabel(item_sit_id: bigint, type: string) {
const uri = this.config.apiHost() + '/living/requestLabel/' + item_sit_id + "?type=" + type;
const obs = this.http.get(uri)
return obs;
}


I call that function in the code:

label(item_sit_id: string) {
const that = this;
this.livingService.requestLabel(this.feature.properties.item_sit_id, this.type).subscribe(function (jsonData) {
const message = jsonData['success'] ? 'successful' : jsonData['message'];
that.snackBar.open(message, 'Label request', {
duration: 2000
});
});
this.bottomSheetRef.dismiss();
}


It works, however IntelliJ marks jsonData['success'] and jsonData['message'] with the error:

TS7053: Element implicitly has an any type because expression of type 'success' can't be used to index type Object
Property success does not exist on type Object


success is a boolean, and message is a string.

What should I be doing to avoid the problem?

Is it an error or warning? Since it works, I'd call it a warning, but IntelliJ marks it as an error.
