TypeError [ERR_INVALID_ARG_TYPE]: The "path" argument must be of type string. Received undefined

This error occurs when a function or method that requires a string argument is passed an undefined value instead. This can happen if the variable containing the path is not properly initialized or if it is not passed as an argument to the function. To fix this error, make sure that the variable containing the path is properly initialized and passed as a string argument to the function.
