local agent dev -> "RPC error: Error: Method toJSON does not exist"

for the life of me, I cannot figure out why this RPC call is failing. Near as I can tell, when toJSON is not available, it means the durable object isn't available? my local DO seems to exist in .wrangler and naming agrees with my wrangler.jsonc, so idk if this is an agent thing or what.

Happy to provide more here, but idk what to share.
