I would like to add, that the correct call for me (at least one that provided results after the hack/fix) was:

const data = JSON.stringify( {
  identifier,
  password
} );

const res = await fetch( `${API_URL}/api/auth/local/`, {
  headers: {
    'Content-Type': 'application/json'
  },
  method: 'POST',
  body: data
} );

And this issue apparently has to do with the upgrade from v8 to v9 for the jsonwebtoken package. There’s a migration guide that explains that they are now validating options.
