AkousaTypeError: x is not iterableA value that is not iterable was used where an iterable was expected, such as in a for...of loop or spread operator.
You used a non-iterable value (like a number, null, undefined, or plain object) in a context that requires an iterable (for...of, spread, destructuring, Array.from). Plain objects are not iterable by default.
Ensure the value is an array, string, Map, Set, or other iterable. For objects, use Object.keys(), Object.values(), or Object.entries(). Check for null/undefined before iterating.
