Subject: [PATCH] Fix Convex validator to accept null for optional string
 fields
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Rust serializes Option<String>::None as null, not undefined.
Updated reportUsbPolicyStatus mutation to accept both null and undefined
for error and currentPolicy fields.
