703-736: 🎯 Functional Correctness | 🔵 Trivial | ⚡ Quick winAdd negative callback-parameter assertions to the indirect-enforcement cases.
The first three objects in the direct block do not contain the
selectcallbacks described by their comments. The twoArray.mapcases both contain the same compatible callback, so neither detects an incompatibleselectparameter.Add the missing positive cases and a
@ts-expect-errorcase for an incompatibleselectparameter on both paths. Test an incompatiblethrowOnErrorparameter only with an explicitTError; otherwisethrowOnErrorinfersTErrorfrom its callback.Suggested coverage additions
{ queryKey: key1, queryFn: () => 'string', + select: (a) => a, }, // however you can add a type to the callback { queryKey: key2, queryFn: () => 'string', + select: (a: string) => parseInt(a), }, // the type you do pass is enforced { queryKey: key3, queryFn: () => 'string', + // @ts-expect-error (select parameter must match queryFn data) + select: (a: number) => a, },Add an analogous
Array.mapcase whoseselectparameter has an incompatible type, and assert it with@ts-expect-error. Add a separate explicit-TErrorcase for incompatiblethrowOnErrorparameters.🤖 Prompt for AI Agents
