NoPermission

The proxy pallet refused the action: the proxied call could escalate privileges, or the caller lacks authority over the pure proxy (e.g. kill_pure by a non-spawner). Check the proxy type's call filter and the original create_pure arguments.

Declared by the Proxy pallet; it classifies to the semantic code not_authorized.

Remediation

Sign with the key or origin that owns the target object, then retry

The same explanation is available in the terminal: btcli explain NoPermission.
