I have to write a entitiesService.add function with the conditions below. I have the image of the bug that I am trying to clear. I have payload in the response but it does not include the id. I need to add id but I am not how since they only let me use the parameter payload.

Bug Picture Link

• The parameters names: payload
• The add function should implement a success handler with a call to .then.
• The function provided to the .then should return capture the newly created id from the response and attach it as a new property to the payload
• The function provided to the .then should return the payload that was originally passed into the top level function

.

entitiesService.add = (payload) => {
    console.log("addEntities is executing", payload);

    const config = {
        method: "POST",
        url: entitiesService.endpoint,
        data: payload,
        crossdomain: true,
        headers: {
            "Content-Type": "application/json"
        },
    };

    return axios(config).then(response => {
        return payload
    })
};
