Oh that’s good sign, it means the canister was deployed but you picked the wrong canister ID. It happened to me too, the dfx output is a bit confusing.
The output is actually the candid explorer output, what you get in your screenshot. The effective canister ID deployed is the one indicated with param id= not the one with canisterId= (see my screenshot here).
So in your above snippet, instead of
identityProvider = "http://127.0.0.1:4943/?canisterId=rkp4c-7iaaa-aaaaa-aaaca-cai&id=r7inp-6aaaa-aaaaa-aaabq-cai
You can probably use
identityProvider = "http://127.0.0.1:4943/?canisterId=r7inp-6aaaa-aaaaa-aaabq-cai
Alternatively, if you don’t care about developing in Safari, you can also use the canisterId as sub-domain like http://r7inp-6aaaa-aaaaa-aaabq-cai.127.0.0.1:4943/.
