Dfx build fails when canister alias doesn't match filename case

On dfx 0.5.11, given this dfx.json:

{
  "canisters": {
    "a": {
      "main": "A.mo",
      "type": "motoko"
    },
    "B": {
      "main": "b.mo",
      "type": "motoko"
    }
}

Running dfx build returns an error:
No actor found, cannot generate JS bindings

Changing the file names to a.mo and B.mo, respectively, fixes it.

Haha what? I’ll look at it tomorrow morning.

Can you try with 0.5.13 (you’ll have to change the package.json to point to @dfinity/agent latest)

Just tried with 0.5.13, same error :confused:

Okay I have a fix in PR, will be in the next release.

Unrelated to the above but I didn’t want to create a new topic:

In the user library, is IDL.PrincipalClass correct? Looks like the encoding is expecting a CanisterId instead

You are correct. The types aren’t right. A CanisterID is a Principal but a Principal can be more. It will be fixed soon.
