Error message

getInspectorDataForViewAtPoint() is not available in production.

What it means

The RN Inspector's getInspectorDataForViewAtPoint depends on dev-only renderer hooks (findNodeHandle/inspect internals) that are compiled out of production bundles; when the surrounding dev-tooling branch is absent, calling it throws. It is a tooling API, not an application API - production builds intentionally have no inspector.

Solutions

1. Gate every call with if (__DEV__).
2. Run inspection only against dev/debug builds.
3. Strip inspector imports from release entry points (Metro transformer / babel plugin) so they are dead-code eliminated.

Example fix

// before
const data = getInspectorDataForViewAtPoint(x, y, callback);

// after
if (__DEV__) {
  getInspectorDataForViewAtPoint(x, y, callback);
}

if (__DEV__) {
  getInspectorDataForViewAtPoint(x, y, callback);
} else {
  // inspection is not available in production; skip or degrade gracefully
}

const canInspect = () => Boolean(__DEV__);

When it happens

Trigger: Calling getInspectorDataForViewAtPoint (directly or through inspector/overlay libraries) in a production RN bundle where __DEV__ is false and the dev-only machinery is stripped.

Common situations: Dev-only inspector integrations left enabled in release builds; QA/overlay tooling that assumes the inspector exists everywhere; libraries calling renderer internals without a __DEV__ guard.
