marshal object %q: %w

Error message

marshal object %q: %w

What it means

Wrapped error from Replicas.MarshalBinary when an individual replica's storobj.Object fails binary serialization during a Replicas batch encode (used in replication transports). The failing object's ID is included; the underlying storobj error is chained.

Solutions

1. Inspect the wrapped error to see which part of the object failed to serialize
2. Check for unsupported property types or oversized payloads on the named object
3. Verify schema/object version compatibility between sender and receiver
