Invalid region code:

Error message

Invalid region code: 

What it means

Same libphonenumber metadata failure, for the Libyan addon (phone-type-formatter.ly.js). R resolves the region against metadata map L and throws Error('Invalid region code: ' + c) when the metadata prototype cannot be built. The empty code means the formatter ran without a valid 'LY' region.

Solutions

  1. Pass 'LY' explicitly as the region when calling the formatter.
  2. Validate the region is a non-empty 2-letter uppercase string before the call.
  3. Default or reject empty region inputs at the validation boundary.
  4. Supply a default country to the parser so the region resolver never receives an empty value.
  5. Regenerate the ly addon so its metadata map contains LY.

Example fix

// before
const formatted = formatter(rawNumber); // no region -> Invalid region code: 
// after
const formatted = formatter(rawNumber, { country: 'LY' });
Defensive patterns

Strategy: validation

Validate before calling

function isValidRegion(r) {
  return typeof r === 'string' && /^[A-Z]{2}$/.test(r.toUpperCase()) && r.trim() !== '';
}
if (!isValidRegion(region)) {
  throw new TypeError(`phone-type-formatter: expected ISO region code, got ${JSON.stringify(region)}`);
}

Type guard

function isRegionCode(v) {
  return typeof v === 'string' && /^[A-Za-z]{2}$/.test(v);
}

Try / catch

let formatted;
try {
  formatted = formatter(number, { country: 'LY' });
} catch (e) {
  if (/Invalid region code/.test(e.message)) {
    formatted = null;
  } else {
    throw e;
  }
}

Prevention

When it happens

Trigger: Calling the bundle-exported formatter with an empty/undefined region argument; the Q constructor invoking R(this, this.D) with an unset region; a country string absent from the bundled metadata (O returns null) triggering the throw.

Common situations: Missing defaultCountry in configuration; empty country field on parsed phone records; using the addon bundle standalone without region wiring; stale metadata after library regeneration.
