fix(react): silence invalid worklet warnings by Yradex · Pull Request #2586 · lynx-family/lynx-stack

Summary by CodeRabbit

Bug Fixes

Removed the "Invalid function object" console warning that appeared when worklet runtime encountered invalid, null, or undefined handler functions. Invalid worklet contexts continue to be properly rejected; only the diagnostic message has been eliminated to reduce unnecessary console output.

Overview

runWorklet can receive invalid or missing main-thread function objects when optional/nullish handlers flow through the worklet event path.
Those values are still ignored by returning early, but the runtime no longer emits the noisy MainThreadFunction: Invalid function object warning.

Key Points

The invalid ctx guard keeps the same control flow: values without _wkltId or _lepusWorkletHash return without executing a worklet.
The console side effect and its JSON.stringify(ctx) work were removed from that early-return path.
The focused runtime test now asserts invalid ctx values do not throw and do not warn.

For example, an event value shaped like { _workletType: "main-thread" } is still treated as non-executable worklet ctx, but it is ignored silently instead of surfacing a developer-console warning.
