Transfer of cookies between the client and the server.

Hello. I use node.js as a layer between php server and client (browser). All requests go through graphql. Everything works well, but there is one problem - i cannot share cookie across graphql from client.
Here is the algorithm of actions:
The user makes a request to the graph and passes the scheme. The graph in the resolve method makes a request to api and passes the cookies. query method fetch api.
const AuthMutation = { type: ResponseType, args: { locale: { type: StringType }, password: { type: StringType }, username: { type: StringType } }, async resolve(parent, args, context) { const body = querystring.stringify(args); const headers = { 'Content-Type': 'application/x-www-form-urlencoded', 'Cookie': cookieToString(context.req.cookies) }; const {object} = await queryFetch(api.gqlAPI.auth, 'POST', headers, body); return object; }, };
how to pass cookies from the 'resolve' method to the client

I found a solution.

in server.js:

app.use('/graphql', (req, res) => {
    return graphqlHTTP({
        schema,
        graphiql: __DEV__,
        context: {req, res},
    })(req, res)
})

example graphql mutation:

const AuthMutation = {
    type: ResponseType,
    args: {
        locale: {
            type: StringType
        },
        password: {
            type: StringType
        },
        username: {
            type: StringType
        }
    },
    async resolve(parent, args, context) {
        const body = querystring.stringify(args);
        const headers = {
            'Content-Type': 'application/x-www-form-urlencoded',
            'Cookie': cookieToString(context.req.cookies)
        };
        const {object} = await new Promise((resolve, reject) => {
            headers["Connection"] = "Keep-Alive";
            fetch(api.gqlAPI.auth, {
                    method: 'POST',
                    credentials: 'same-origin',
                    cache: 'no-cache',
                    headers: headers,
                    ...(body ? {body: body} : null),
                }
            ).then((response) => {
               // Recording the cookies received from the php server in response to the graphql
                context.res.set('set-cookie', response.headers.get('set-cookie'))
                if (response.status >= 200 && response.status < 300) {
                    return Promise.resolve(response);
                } else {
                    return Promise.reject(response.status);
                }
            }).then((response) => {
                return response.json()
            }).then((response) => {
                return resolve(response);
            }).catch((error) => {
                reject(error);
            });
        });
        return object;
    },
};
