Error message

parsing geo location: %w

What it means

browserContext.setGeolocation(geolocation) exports its argument to common.Geolocation - a flat object with numeric latitude, longitude, and optional accuracy fields. A shape Sobek cannot export to that struct (a string, array, non-numeric coordinates, or wrong key names) fails conversion and surfaces wrapped in this error before any CDP traffic.

Solutions

1. Use the exact keys with numbers: setGeolocation({ latitude: 48.8584, longitude: 2.2945 })
2. Include accuracy only as a number if needed: { latitude, longitude, accuracy: 100 }
3. Omit the call entirely to keep the browser default geolocation

Example fix

// before: abbreviated keys -> export fails
await context.setGeolocation({ lat: 48.85, lng: 2.29 });

// after: exact field names with numeric values
await context.setGeolocation({ latitude: 48.8584, longitude: 2.2945 });

const geo = { latitude: 48.8584, longitude: 2.2945 };
const ok = [geo.latitude, geo.longitude].every((n) => typeof n === 'number' && Number.isFinite(n));
if (!ok) throw new TypeError('geolocation requires numeric latitude/longitude');
await context.setGeolocation(geo);

function isGeolocation(v) {
  return (
    typeof v === 'object' &&
    v !== null &&
    !Array.isArray(v) &&
    typeof v.latitude === 'number' &&
    typeof v.longitude === 'number' &&
    (v.accuracy === undefined || typeof v.accuracy === 'number')
  );
}

try {
  await context.setGeolocation(geo);
} catch (e) {
  if (String(e).includes('parsing geo location')) {
    console.warn('invalid geolocation shape - skipping');
  } else throw e;
}

When it happens

Trigger: setGeolocation('Paris'); setGeolocation(48.85); setGeolocation({ lat: 48.85, lng: 2.29 }) (wrong keys - the struct wants latitude/longitude); nested coordinate objects.

Common situations: Using abbreviated lat/lng key names from other geolocation APIs; passing a coordinates array from a mapping library; copy-pasting Playwright snippets with extra properties.
