Fix EvalError
in Playwright
✅ Solution
This EvalError often occurs when playwright tries to serialize a complex object or function to be executed in the browser context, and that object or function cannot be directly converted to a string. To fix this, ensure that any arguments passed to page.evaluate() are JSON serializable. If you are passing functions, consider passing their string representation instead, or redesigning your approach to avoid serializing complex logic.
