The error data property of a SuppressedError instance contains a reference to the error that results in the suppression.

Value

Any value. Like cause, you cannot assume it's an Error instance, although it usually is the case.

Examples

Using error

try {
  throw new SuppressedError(
    new Error("New error"),
    new Error("Original error"),
    "Hello",
  );
} catch (e) {
  console.log(e.error); // Error: "New error"
}
