geolocation.longitude: precondition -180 <= LONGITUDE <= 180

Error message

geolocation.longitude: precondition -180 <= LONGITUDE <= 180 failed.

What it means

`verifyGeolocation` enforces longitude within [-180, 180]. Out-of-range values throw with this precondition-style message. Geolocation is set via `newContext({ geolocation })` or `context.setGeolocation()`.

Solutions

1. Clamp longitude to [-180, 180] before passing
2. Validate config/user input against the range and reject early with a clearer error

Example fix

// before
await context.setGeolocation({ longitude: 200, latitude: 40 });

// after
await context.setGeolocation({ longitude: 200 % 360, latitude: 40 });
// or clamp: Math.max(-180, Math.min(180, lon))

function clampLongitude(lon: number): number {
  if (lon < -180 || lon > 180) {
    // normalize or clamp:
    return Math.max(-180, Math.min(180, lon));
  }
  return lon;
}
await context.setGeolocation({ longitude: clampLongitude(lon), latitude });

When it happens

Trigger: `context.setGeolocation({ longitude: 200, latitude: 0 })` or `newContext({ geolocation: { longitude: -181, latitude: 0 } })`.

Common situations: Off-by-one sign errors; data sourced from configs/databases with unverified ranges; copy-paste of coordinates with missing decimal points.
