[custom formatter threw an exception]

Then, i tried without the --bun argument (bunx next build) and it worked. But when i run my website with bunx --bun next start it works, but when i enter a page that was working it doesnt work. (500 Internal Server Error) and it prints ⨯ [custom formatter threw an exception]
