Request ID not set.

Error message

Request ID not set.

What it means

Geofence.Builder.build() assembles the Geofence and validates all required fields; it throws IllegalArgumentException when setRequestId(String) was never called, so the request ID is missing. This guard is part of build()'s completeness validation of required parameters.

Solutions

1. Call setRequestId(...) before build()
2. Default the request id to a stable app-defined identifier when none is supplied
