Convert Candid to JSON

I will put some work into examples. With a bit of luck I will encounter any issues you are seeing and be able to iron them out.

awesome, thank you for looking into this!

@bitdivine btw I am also getting issues using ic_agent package in rust. This is how I setup the call to made for read_state_canister_metadata

let metadata: Vec<u8> = ic_agent::agent::Agent::read_state_canister_metadata(
    &"candid:service".to_string() // Not sure if this is the correct one

I had to include getrandom = { version = "0.2", features = ["js"] } but after deploying I am getting 2 errors

Also getting non-exhaustive patterns: Some(_) not covered from ic-agent 0.29.0

I am experiencing the same issue with ic-agent.

Hello all. I’m really sorry, I’ve not been able to make any progress on this. I am working like crazy on several things and I’m not getting enough sleep, let alone a few hours to address this. Maybe I’ll get a breather over Christmas and I can look into this then.

hey bumping this, did anybody fix the non-exhaustive pattern error?

Ignore this - turns out we were using the canister builder when it was the wrong package… should have just used the management canister interface.
