TypeError: More arguments needed
The JavaScript exception "more arguments needed" occurs when there is an error with how a function is called. More arguments need to be provided.
Message
TypeError: argument is not an Object and is not null (Edge) TypeError: Object.create requires at least 1 argument, but only 0 were passed TypeError: Object.setPrototypeOf requires at least 2 arguments, but only 0 were passed TypeError: Object.defineProperties requires at least 1 argument, but only 0 were passed
Error type
What went wrong?
There is an error with how a function is called. More arguments need to be provided.
Examples
Required arguments not provided
The Object.create()
method requires at least one argument and the Object.setPrototypeOf()
method requires at least two arguments:
var obj = Object.create(); // TypeError: Object.create requires at least 1 argument, but only 0 were passed var obj = Object.setPrototypeOf({}); // TypeError: Object.setPrototypeOf requires at least 2 arguments, but only 1 were passed
You can fix this by setting null
as the prototype, for example:
var obj = Object.create(null); var obj = Object.setPrototypeOf({}, null);
