So this might have been super obvious to other folks out there but it
wasn't for me. You can get at the original GraphQLResult
<https://aws-amplify.github.io/amplify-js/api/interfaces/graphqlresult.html> by
looking at the *error.promise* and *error.rejection*. So in your handleError
method:
---------------------
isGraphQLResult(rejection: any): boolean {
return rejection !== undefined && (rejection.data !== undefined ||
rejection.errors !== undefined);
}
handleError(error: any): void {
if (error !== undefined && this.isGraphQLResult(error.rejection)) {
const graphqlResult: GraphQLResult = error.rejection as GraphQLResult;
// handle the graphqlResult
}
}
---------------------
Honestly didn't know that *error.promise* and *error.rejection* were even
there ... I guess I missed the memo on that one.
