Description

The getAuth() "Clerk can't detect usage of clerkMiddleware()" error emitted a stray double space before its first bullet, so users saw - clerkMiddleware() is used in your Next.js middleware or proxy file. (two spaces after the dash).

In authAuthHeaderMissing, the first bullet's prefixSteps ternary fell back to ' ' (a single space) when prefixSteps was undefined — which is the getAuth() path. It's the only caller that passes undefined; auth() always passes an array (even an empty one, which is truthy), so it never hit this branch. Combined with the literal - already at the start of the line, the fallback produced a double space. This changes it to '' so that path renders - clerkMiddleware() is used... with a single space, matching the docs page for this error. The prefixSteps-provided branch (App Router src-directory hint) is unchanged.

…rror
The default auth() case rendered "- clerkMiddleware()..." with two spaces
because the prefixSteps ternary fell back to a single space combined with the
literal "- " prefix. Fall back to an empty string so the first bullet renders
with a single space, matching the docs.

The getAuth() "Clerk can't detect usage of clerkMiddleware()" error emitted a stray double space before its first bullet, so users saw - clerkMiddleware() is used in your Next.js middleware or proxy file. (two spaces after the dash).

In authAuthHeaderMissing, the first bullet's prefixSteps ternary fell back to ' ' (a single space) when prefixSteps was undefined — which is the getAuth() path. It's the only caller that passes undefined; auth() always passes an array (even an empty one, which is truthy), so it never hit this branch. Combined with the literal - already at the start of the line, the fallback produced a double space. This changes it to '' so that path renders - clerkMiddleware() is used... with a single space, matching the docs page for this error. The prefixSteps-provided branch (App Router src-directory hint) is unchanged.

Description

The getAuth() "Clerk can't detect usage of clerkMiddleware()" error emitted a stray double space before its first bullet, so users saw - clerkMiddleware() is used in your Next.js middleware or proxy file. (two spaces after the dash).

In authAuthHeaderMissing, the first bullet's prefixSteps ternary fell back to ' ' (a single space) when prefixSteps was undefined — which is the getAuth() path. It's the only caller that passes undefined; auth() always passes an array (even an empty one, which is truthy), so it never hit this branch. Combined with the literal - already at the start of the line, the fallback produced a double space. This changes it to '' so that path renders - clerkMiddleware() is used... with a single space, matching the docs page for this error. The prefixSteps-provided branch (App Router src-directory hint) is unchanged.

The default auth() case rendered "- clerkMiddleware()..." with two spaces

Description

The getAuth() "Clerk can't detect usage of clerkMiddleware()" error emitted a stray double space before its first bullet, so users saw - clerkMiddleware() is used in your Next.js middleware or proxy file. (two spaces after the dash).

In authAuthHeaderMissing, the first bullet's prefixSteps ternary fell back to ' ' (a single space) when prefixSteps was undefined — which is the getAuth() path. It's the only caller that passes undefined; auth() always passes an array (even an empty one, which is truthy), so it never hit this branch. Combined with the literal - already at the start of the line, the fallback produced a double space. This changes it to '' so that path renders - clerkMiddleware() is used... with a single space, matching the docs page for this error. The prefixSteps-provided branch (App Router src-directory hint) is unchanged.

…rror
The default auth() case rendered "- clerkMiddleware()..." with two spaces
because the prefixSteps ternary fell back to a single space combined with the
literal "- " prefix. Fall back to an empty string so the first bullet renders
with a single space, matching the docs.

Description

The getAuth() "Clerk can't detect usage of clerkMiddleware()" error emitted a stray double space before its first bullet, so users saw - clerkMiddleware() is used in your Next.js middleware or proxy file. (two spaces after the dash).

In authAuthHeaderMissing, the first bullet's prefixSteps ternary fell back to ' ' (a single space) when prefixSteps was undefined — which is the getAuth() path. It's the only caller that passes undefined; auth() always passes an array (even an empty one, which is truthy), so it never hit this branch. Combined with the literal - already at the start of the line, the fallback produced a double space. This changes it to '' so that path renders - clerkMiddleware() is used... with a single space, matching the docs page for this error. The prefixSteps-provided branch (App Router src-directory hint) is unchanged.

…rror
The default auth() case rendered "- clerkMiddleware()..." with two spaces
because the prefixSteps ternary fell back to a single space combined with the
literal "- " prefix. Fall back to an empty string so the first bullet renders
with a single space, matching the docs.

The authAuthHeaderMissing error message now omits the empty bullet-prefix line when prefixSteps is absent. A patch changeset documents the correction for @clerk/nextjs.

Add a regression test for getAuthAuthHeaderMissing().

createGetAuth() uses this helper with undefined, which is the call path affected by the fallback change. The App Router auth() path passes [] and does not exercise the fallback.
