Error caused by missing field used as keyField in cache is shadowed

[jelhan]

I had an error caused by not querying a field, which was used as keyField in InMemoryCache configuration. It throw the following error:

    Invariant Violation: Missing field 'name' while extracting keyFields from {"foo": "bar","__typename":"Post"}

Debugging was very challenging because that error is shadowed. I was able to get that error by putting a breakpoint here:

glimmer-apollo/packages/glimmer-apollo/src/-private/query.ts

Lines 75 to 90 in 1e507ec

	this.#subscription = observable.subscribe(
	(result) => {
	this.#onComplete(result);
	if (firstResolve) {
	firstResolve();
	firstResolve = undefined;
	}
	},
	(error) => {
	this.#onError(error);
	if (firstReject) {
	firstReject();
	firstReject = undefined;
	}
	}
	);

The error was not logged in console. QueryResource.error was undefined.
