VistasApollo GraphQL Client + Next.JS Error Handling
The component renders the error state just fine, but the exception is displayed as uncaught in the console and a dialogue is displayed in next dev on the browser. Is there a way to handle expected errors to squelch this behavior?
import { useMutation, gql } from "@apollo/client";
import { useEffect } from "react";
const CONSUME_MAGIC_LINK = gql`
mutation ConsumeMagicLink($token: String!) {
consumeMagicLink(token: $token) {
token
member {
id
}
}
}
`;
export default function ConsumeMagicLink({ token }) {
const [consumeMagicLink, { data, loading, error }] =
useMutation(CONSUME_MAGIC_LINK);
console.log("DATA", data, "loading:", loading, "error:", error);
useEffect(() => {
try {
consumeMagicLink({ variables: { token } });
} catch (e) {
console.log(e);
}
}, []);
var text = "Link has expired or has been used previously";
if (data) text = "SUCCESS: REDIRECTING";
if (loading) text = "Processing";
if (error) text = "Link has expired or has been used previously";
return (
<div>
<h2>{text}</h2>
</div>
);
}

The error is from the client instead of the mutation so your try-catch cannot catch it. To handle this you can add the error handling to the client, for example:
const errorLink = onError(({ graphQLErrors, networkError }) => {
if (graphQLErrors)
graphQLErrors.forEach(({ message, locations, path }) =>
console.log(
`[GraphQL error]: Message: ${message}, Location: ${locations}, Path: ${path}`,
),
);
if (networkError) console.log(`[Network error]: ${networkError}`);
});
const httpLink = new HttpLink({
uri: "some invalid link"
});
const client = new ApolloClient({
link:from([httpLink,errorLink]),
cache: new InMemoryCache()
})
And as you got authorization error, I suggest you check your headers.
You can find additional information and examples of this approach here: enter link description here
