empty-client-namespace

Id

@azure-tools/typespec-client-generator-core/empty-client-namespace

Severity: warning

This diagnostic is issued when @clientNamespace is given an empty or whitespace-only value.

Impact

• Area: SDK namespace customization. Generation continues, but the empty @clientNamespace override cannot place generated declarations in a custom namespace.
• Not affected: Model names, operation routes, and payload serialization are unchanged.

❌ Incorrect Usage

@clientNamespace(" ") // client namespace is empty/whitespace
model Widget {}

Diagnostic Message

TCGC reports:

Cannot pass an empty value to the @clientNamespace decorator

✅ How to Fix

Provide a non-empty namespace string or remove @clientNamespace.

@clientNamespace("Contoso.Widgets")
model Widget {}

Suppression

This diagnostic should not be suppressed. Give @clientNamespace a non-empty value, or remove the decorator.
