```
thread 'main' panicked at 'activated_features for invalid package: features did not find PackageId { name: "actor-echo-module", version: "0.1.0", source: "/home/rvolosatovs/src/github.com/wasmCloud/wasmCloud/tests/actors/echo-module" } NormalOrDev', src/tools/cargo/src/cargo/core/resolver/features.rs:321:14
