Type 'string' is not assignable to type [object]

I have an interface as follows:

interface Order {
 symbol: string
 side: string
 price: number
 quantity: number
}

I have a line in my code where I am accessing values in a table. However, it complains and says that d.symbol is not assignable to a string.

accessor:  (d: Order) : Order  =>  d.symbol

Does anyone know how I can work around this?

You returned a string when you declared that the return type is Order.

Solution: change the return type to string.

(d: Order) : Order  =>  d.symbol

This line means "A function accepting one argument (d) of type Order that returns an Order".

Your function returns a string, not an Order.

You can fix the return type annotation

(d: Order) : string  =>  d.symbol

Or remove it

(d: Order) =>  d.symbol

Or return the correct kind of thing, if that's what was actually intended

(d: Order) : Order  =>  d
