How to call IC from the rust agent package

Yeah that’s true
I tried to deploy a canister on the Beta Mainnet now, but it’s not possible just yet as is described here:

Developer setup best practices testing/deploying canisters to new beta-mercury network

Hello @der0pa, Currently there are no subnets for public app deployment available. As the network is still bootstrapping application subnets will be rolled out in the coming weeks. In the meantime you can work on your projects by building and deploying locally. The local quickstart here would be the one to follow for this: Local development :: Internet Computer

Therefore, I’m deploying locally for now. Calling the query with

let response = query_builder.with_arg("everyone".to_string()).call().await;

returned this error: IDL error: missing magic bytes.

Changing the string to .with_arg("DIDLeveryone".to_string()) as you suggested here:

Any specifications on the HTTP API / cbor message?

Hi David, We don’t (yet) officially support other languages or making custom calls to the client, but I can let you in on a secret bit; the IDL (the argument encoding) is normally prefixed by DIDL as the magic bits. The encoding is not yet ready to open source, so if you want to pass in data you’d have to reverse engineer it yourself. In the meantime, an empty field should be encoded as DIDL\0\0. Your Motoko code will not get any arguments. Hope this helps!

got me to the next error: IDL error: too many types.
I’m not sure what it means though.
Is there maybe some other convention from candid that needs to be considered?
