Thanks for the PR.

Does this mean the tuling API client changed its behaviour?

I found that tuling123'api is not changed. This example always run error.

I check this module. Tuling123'api ask always return Promise. And Now, the tuling bot's result is {code: number, text: string}. you should have a try.

Test case is not pass. I don't know why. I'm not change other file. This testcase is not pass in
test/fixture/docker/type-error.ts file:

let i = 3
i = "should set to string because it's type is number"
console.log(i)
