			why: "`useFetch` failed to hash the request body for the cache key.",
			fix: "Pass a serializable value (plain object, string, FormData) as the request body, or provide an explicit `key` to `useFetch`.",
			docs: false
		},
		NUXT_E3003: {
			why: "`useAsyncData`/`useFetch` was called after the component had already mounted, so the data fetch cannot be awaited during setup.",
			fix: "Use `$fetch()` for requests triggered after mount (e.g. in event handlers), or call `useAsyncData`/`useFetch` in the `setup()` function.",
			docs: false
		},
		NUXT_E3004: {
			why: (p) => `Incompatible options detected for "${p.key}":\n${p.warnings}`,
			fix: "You can use a different key or move the call to a composable to ensure the options are shared across calls.",
			docs: false
		},
		NUXT_E3005: {
			why: "`execute` was passed directly to `watch`, which causes unintended behavior.",
			fix: "Wrap the call: `watch(source, () => execute())` instead of `watch(source, execute)`.",
			docs: false
		},
		NUXT_E3006: {
			why: (p) => `\`${p.fn}\` handler returned \`undefined\`, so the request may be duplicated on the client side.`,
			fix: "Return a value from the handler function (e.g. `return null` instead of returning nothing).",
			docs: false
		},
		NUXT_E3007: {
			why: "`asyncData` returned a non-object value.",
			fix: "Return a plain object from the `asyncData()` function, e.g. `asyncData() { return { key: value } }`.",
			docs: false
		},
		NUXT_E3008: {
			why: "`useAsyncData` key must be a non-empty string.",
			fix: "Pass a non-empty string as the first argument to `useAsyncData()`."
		},
		NUXT_E3009: {
			why: "`useAsyncData` handler must be a function.",
			fix: "Pass a function as the handler argument, e.g. `useAsyncData('key', () => $fetch('/api/data'))`."
