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
- Call setRequestId(...) before build()
- Default the request id to a stable app-defined identifier when none is supplied
Defensive patterns
Strategy: validation
