Frida allows you to run JavaScript code within the context of a target application, enabling interaction with its components.When sending byte arrays from Frida JS to a Python script, a common error like 'Error: expected a pointer' may occur.To resolve this error, convert the byte array to a Base64 string in JavaScript before sending it back to Python.In Python, decode the Base64 string back into a byte array for further processing and effective data handling in hybrid environments.
