insert query are cached about storage

[vvo]

Correction: POST requests are being cached at the moment yep even in server actions. I wrongly linked request memoization (which is a different feature).

The suggestion from @luismeyer should work. And in a future Next.js release POST in server actions won't be cached anymore.

Getting the same issue when trying out the Next.js learn tutorial. Making the same INSERT or UPDATE query twice results in only one query ever executing.

When I delete the cache directory in next it works again so it's definitely that. Maybe I should post on next github ?

hey @smailio,
this is expected, since all fetch requests on the server are cached by Next.js by default (docs)

Ways to fix this could be:

• opt out of the data cache with unstable_noStore (docs)
• call revalidatePath or revalidateTag to purge the cache manually (docs)

@smailio @luismeyer From reading the docs, only GET methods are being cached in Next.js App Router ("Good to know" from https://nextjs.org/docs/app/building-your-application/caching#request-memoization).

And our database client uses POST (https://github.com/neondatabase/serverless/blob/947e5b107f3f3f9c9af1f769d3d7e63a49a43e96/export/httpQuery.ts#L162-L167). So something else is doing caching here, could it be some server action custom behavior?
