Type error in client config

[iBobik]

Everything works well except this Typescript error in the nuxt.config.ts:

Type 'string' has no properties in common with type 'RuntimeValue<Overrideable<{ type: string; name: string; value: any; }, "_PUBLIC_GRAPHQL_CLIENT_CLIENTS_DEFAULT_TOKEN">, "You can override this value at runtime with NUXT_PUBLIC_GRAPHQL_CLIENT_CLIENTS_DEFAULT_TOKEN">'.ts(2559)

It happens in multiple of my projects, but not when I pasted this config in repro on the Stackblitz.

Any ideas what to do with it?
