one/src/platform/nativeError.ts

One is a React framework for web, iOS, and Android apps.

// native failures cross nitro as one message, "<code>: <Namespace>.<verb>:
// <detail>", and android appends a newline to every rejection. sync throws add
// a "<Hybrid>.<method>(...): " prefix ahead of the code instead. this trims
// the newline and restores the stable code on the error the caller sees, so
// callers branch on `code` as they did with the bridge modules.
