Threw `undefined` / `null`

Why This Error Occurred

Somewhere in your code you throw an undefined or null value. Since this isn't a valid error there isn't a stack trace. We show this error instead to let you know what to look for.

function getData() {
  let error
  throw error
}
 
function Page() {
  const error = data?.error || null
  throw error
}

Possible Ways to Fix It

Look in your pages and find where an error could be throwing undefined or null values and ensure new Error() is used instead.
