[Vue tip]: ${msg}

Error message

[Vue tip]: ${msg}

What it means

Generic tip output in the weex framework build: tip() prints non-error guidance messages prefixed with '[Vue tip]:' via console.warn when config.silent is false (unless a custom warnHandler-like path intercepts). It is not a thrown error; it marks compiler/runtime advice such as deprecations or best-practice hints attached to a component trace.
