Yes, it turns out the problem was class actor canisters can’t be imported with `canister:`, which is the only way I found the docs and examples made reference to:

> [@Import "canister: canistername" error](https://forum.dfinity.org/t/import-canister-canistername-error/6225/2):
>
> I had this the other day. Is your canister a class? You can’t import it with canister:. You need to create an actor type that conforms to the actor interface and seed it with a hardcoded principal.

By using the service pattern, it worked. In my case:

` let icrc_token_canister = actor ("r7inp-6aaaa-aaaaa-aaabq-cai") : ICRCTypes.TokenInterface;`

@Vivienne If you have any say in the docs / examples, I suggest making clear that

`import AAA "canister:aaa";`

does not and cannot work with class actors. I spent quite a while trying to make `canister:` work yesterday.
