Error message

Invalid `event`.

What it means

Error "Invalid `event`." thrown in facebook/react.

Source

Thrown at packages/react-native-renderer/src/legacy-events/EventPluginUtils.js:182

/**
 * Execution of a "direct" dispatch - there must be at most one dispatch
 * accumulated on the event or it is considered an error. It doesn't really make
 * sense for an event with multiple dispatches (bubbled) to keep track of the
 * return values at each dispatch execution, but it does tend to make sense when
 * dealing with "direct" dispatches.
 *
 * @return {*} The return value of executing the single dispatch.
