Summary

In the Inspector's Functions tab, malformed JSON makes Invoke fail without a visible error. After a successful call, the previous green result remains without feedback about the failed attempt.

Display the parsing error below the arguments input and clear it when the input changes. Keep the previous result visible alongside the current error.

 on Invoke with invalid JSON
- throw from the UI handler without visible feedback
+ display an inline parsing error associated with the input

Evidence

• Before: Enter { and click Invoke. No error appears, and any previous successful result remains.
  After: The panel shows Invalid JSON arguments: … alongside the previous result. Editing clears the error, and corrected arguments invoke successfully.
• Two Storybook interaction cases passed for first invalid input, correction and retry, scalar argument coercion, and invalid input with a previous successful result. They also assert that malformed input does not dispatch an invocation.
• Live Inspector checks passed for parsing feedback, recovery, server-validation errors, and keyboard invocation. Error feedback was inspected in light and dark themes.
• All local gates passed: pnpm lint, pnpm knip, pnpm test, pnpm typecheck, and pnpm build. Tests: 1755 passed, 13 skipped.

Merge Danger

Door: two-way

The change can be reverted without a data migration or public API change.

Blast Radius: Inspector

The shared FunctionRow gains an optional error prop. Functions supplies it; Client keeps its existing behavior. Argument coercion, RPC result handling, and invocation restrictions remain unchanged.

Fixes missing error feedback when users enter invalid JSON and click Invoke on the Functions page.
