Invalid tab: ${finalSearchParams.tab}

Error message

Invalid tab: ${finalSearchParams.tab}

What it means

Thrown by the Voronoi `getPostItems` helper when the `tab` parameter, after uppercasing, is not one of the values in the `TabMap` object (`POPULAR`, `DISCUSSED`, `VIEWED`). The check uses `Object.values(TabMap).includes()`. This is a generic `Error`. Note the `TabMap` keys are lowercase kebab (`most-popular`) but the values are uppercase (`POPULAR`) — this validation checks the value side.

Solutions

1. Use one of `POPULAR`, `DISCUSSED`, or `VIEWED` as the tab value (uppercase).
2. In the popular route, use the lowercase path keys: `most-popular`, `most-discussed`, `most-viewed`.
3. If calling `getPostItems` directly, map through `TabMap` first.

Example fix

// before
tab: 'TRENDING'
// after
tab: TabMap['most-popular']  // 'POPULAR'

const VALID_TABS = Object.values(TabMap); // ['POPULAR', 'DISCUSSED', 'VIEWED']
if (tab && !VALID_TABS.includes(tab.toUpperCase())) {
    throw new InvalidParameterError(`Invalid tab: ${tab}. Valid: ${VALID_TABS.join(', ')}`);
}

function isValidTabValue(tab: string): tab is 'POPULAR' | 'DISCUSSED' | 'VIEWED' {
    return Object.values(TabMap).includes(tab.toUpperCase() as any);
}

When it happens

Trigger: Calling `getPostItems({ tab: 'TRENDING' })` or any uppercase string not in `TabMap`'s values. In the popular route, the `tab` path parameter is mapped from its lowercase key (e.g. `most-popular`) to its uppercase value (e.g. `POPULAR`) before calling `getPostItems`, so a valid popular-route tab should always pass this check — unless `getPostItems` is called directly with a bad value.

Common situations: A code change in the popular route passes an unmapped tab value, or a developer calls `getPostItems` directly with a raw user input. The popular route (line 34) has its own separate `Object.hasOwn(TabMap, ...)` check that guards against this before the mapping.
