Unknown scorecard bloc preset: ${preset}

Error message

Unknown scorecard bloc preset: ${preset}

What it means

resolveBlocSelection validates the preset name against the SCORECARD_BLOC_PRESETS record (USMCA, EU27, ASEAN, BRICS, etc.) and throws this error for any preset string not present as a key. Preset names are case-sensitive and exact; typo'd, lowercased, or deprecated preset ids are rejected so callers always get an official, curated member list.

Solutions

1. Use an exact preset id from SCORECARD_BLOC_PRESETS (e.g., 'USMCA', 'EU27'), case-sensitive.
2. Discover valid ids at runtime from the API's preset listing instead of hardcoding strings.
3. For user-typed input, normalize and map to the closest valid id before sending, or switch to a custom members list instead.
4. If a preset was renamed or removed, migrate to the new id (e.g., NAFTA → USMCA).

Example fix

// before
resolveBlocSelection({ preset: 'eu27' }); // throws: not a key
// after
const id = presetName.trim().toUpperCase() === 'EU' ? 'EU27' : presetName;
if (!(id in SCORECARD_BLOC_PRESETS)) throw new Error(`Unknown preset ${id}`);
resolveBlocSelection({ preset: id });

const VALID_PRESETS = ['USMCA','EU27','ASEAN','BRICS']; // fetch dynamically when possible
if (!VALID_PRESETS.includes(preset)) throw new Error(`Unknown preset: ${preset}`);

function isBlocPreset(p: string): p is keyof typeof SCORECARD_BLOC_PRESETS {
  return p in SCORECARD_BLOC_PRESETS;
}

try {
  const bloc = await getBlocScorecard({ preset });
} catch (err) {
  if (err.message.startsWith('Unknown scorecard bloc preset')) {
    return badRequest(`preset must be one of: ${Object.keys(SCORECARD_BLOC_PRESETS).join(', ')}`);
  }
  throw err;
}

When it happens

Trigger: Calling getBlocScorecardWithReader with preset set to a string not in SCORECARD_BLOC_PRESETS: 'eu27' (lowercase), 'E.U.', 'EU' (not the exact 'EU27'), 'NAFTA' (renamed to USMCA), an empty-after-trim string when members is also empty (that hits the XOR error first), or a preset id removed in a newer API version.

Common situations: 1) Client hardcodes an outdated preset name after a rename (NAFTA→USMCA); 2) case mismatch from user-typed input; 3) version drift where server added/removed presets and the client uses an old list; 4) localization code translating preset labels back into the request field instead of sending the id.
