toast.promise with axios can't handle error codes

[tomerkal]

I am trying to wrap an axios.post call with toast.promise. My basic setup is:

await toast.promise(axios.post(`${API_URL}`, req),
            {loading: "Loading...", success: (res) => res.data.message, error: (res) => res.data.message},
            {position: "top-right"})

When I get a success Response from the server it works good (first shows loading then success message). The problem is when I get a response with an error code, I get a runtime error for the whole app instead of the error toast.
When I tried to avoid this by giving a 200 code for the error response the app didn't crash, but the error message was in a success toast...
The responses also have a "success" field which I can use to handle this manually (choosing between success and error toasts) but then I will need to handle the loading as well.
Is this a problem with how axios is handling error codes or am I doing something wrong?
Thanks alot!
