fixed the problem: fetch() was missing inside httpBatchLink this was missing:
// ...
httpBatchLink({
url: getUrl(),
fetch(url, options) {
return fetch(url, {
...options,
credentials: "include",
});
},
}),
// ...
// ...
httpBatchLink({
url: getUrl(),
fetch(url, options) {
return fetch(url, {
...options,
credentials: "include",
});
},
}),
// ...
