I have the same issue and it was introduced after I added getServerSideProps to my page. I am doing an API call and returning the response:

export const getServerSideProps = async ({ req }) => { const posts = await getAllFeedPosts(req) return { props: { posts } } }

I’m having the same problem:

I’ve got a query params-based state that should be changed after a select value was changed. And this error occurs regularly - not all the time though.

I’m navigating to /foo and changing the input, which should set the bar parameter to baz, so we should end up at /foo?bar=baz.

Is anyone working on this already?
