Id

@azure-tools/typespec-client-generator-core/conflict-access-override

Severity: warning

This diagnostic is issued when an @access override conflicts with access already calculated from an operation or another @access override.

Impact

• Area: Generated SDK visibility. Generation continues using the access level TCGC calculated from operations or earlier overrides, so the conflicting override may not hide the type.
• Not affected: Serialization, wire payloads, and service routes are unchanged.

❌ Incorrect Usage

@access(Access.internal) // conflicts with public access inferred from `op test`
model A {}

op test(@body body: A): void;

Diagnostic Message

TCGC reports:

@access override conflicts with the access calculated from operation or other @access override.

✅ How to Fix

Align access settings so each generated type has one consistent access level, or remove the conflicting override.

@access(Access.internal)
model A {}

@access(Access.internal)
op test(@body body: A): void;

Suppression

This diagnostic should not be suppressed. Make the access settings consistent so the type has a single access level.
