revalidateTag Single Argument Deprecated

Why This Error Occurred

You are using revalidateTag without providing the second argument, which is now deprecated. The function now requires a second argument to specify the revalidation behavior.

Possible Ways to Fix It

Option 1: Add the second argument

Update your revalidateTag calls to include the second argument "max":

// Before (deprecated)
revalidateTag('posts')
 
// After
revalidateTag('posts', 'max')

Option 2: Use updateTag in Server Actions

If you're calling this from a Server Action and need immediate expiration for read-your-own-writes, use updateTag instead:

// In a Server Action
import { updateTag } from 'next/cache'
 
export async function createPost() {
  // ... create post ...
 
  // Immediately expire the cache
  updateTag('posts')
}

Revalidation Behavior

revalidateTag(tag, "max") (recommended): The tag entry is marked as stale, and the next time a resource with that tag is visited, it will use stale-while-revalidate semantics. This means the stale content is served while fresh content is fetched in the background.
revalidateTag(tag, profile): For advanced usage, you can specify any cache life profile that your application has defined in your next.config instead of "max", allowing for custom revalidation behaviors.
updateTag(tag): Only available in Server Actions. The tag entry is expired immediately, and the next request to that resource will be a blocking revalidate/cache miss. This ensures read-your-own-writes consistency.
revalidateTag(tag) without second argument (deprecated): Same behavior as updateTag but shows this deprecation warning.
