Architect#scheduleBuilder or context.scheduleBuilder results in incorrect target on context

Inizia da packages/angular_devkit/architect/src/index_spec.ts e riproduci il fallimento usando yarn bazel test //packages/angular_devkit/architect:architect_test. Segui il contesto del builder attraverso packages/angular_devkit/architect/src/create-builder.ts, indicato dallo stack, e verifica che scheduleBuilder fornisca un target corrispondente alla sua interfaccia TypeScript dichiarata. Il lavoro è completato quando il test mirato di architect ha esito positivo con un target valido.

Is this a regression?

Not that I know of

Description

If a builder is executed via architect.scheduleBuilder, that builder is passed a context that doesn't match the declared interface in typescript. The same happens when using context.scheduleBuilder if no target is passed via the scheduleOptions.

console.log(context.target);
// logs {project: undefined, target: undefined, configuration: undefined}
// but type is {project: string, target: string, configuration?: string} | undefined

🔬 Minimal Reproduction

Run yarn bazel test //packages/angular_devkit/architect:architect_test with the following patch:
