Mixed `notFound` and `redirect`
Why This Error Occurred​
In one of your page's getStaticProps or getServerSideProps notFound and redirect values were both returned.
These values can not both be returned at the same time and one or the other needs to be returned at a time.
Possible Ways to Fix It​
Make sure only notFound or redirect is being returned on your page's getStaticProps or getServerSideProps
