you need to show some code

but it's likely that you did something like fetch("/api/user") in a server component, then it doesn't work because the api route isn't running during build, see https://nextjs-discord-common-questions.joulev.dev/fetching-own-api-endpoint-in-react-server-components

[crimson badge]

yes i have fetch("/api/user")

[exotic quiver]

yes then that doesn't work, see the linked page for more information

if i do this i will get error like Prisma cant run on this browser something like that

[exotic quiver]

this must be in a server component for it to work

[crimson badge]

Yes but for this component what's the solution ?

[exotic quiver]

use a structure similar to this #1121791826521768079 message

you fetch the data in a component and render it in another

[exotic quiver]

this file works fine though because it is a client component so /api/getBarbers is available when it is run

the file that caused the error is a different file

[crimson badge]

Yes i did that and if you remember i had this problem and i could solve it

[crimson badge]

what file you think?

[exotic quiver]
