Warning: Accessing non-existent property 'tracing' of module exports inside circular dependency" when using ttypescript as compiler for ts-jest

[IsaacMcIntyre]

Apologies if this repo is not the right place to post, I wasn't quite sure to post this under ttypescript, or to have it under ts-jest.

I have an issue in where I am seeing many warnings upon running my jest unit tests for my Vue3 project only when ttypescript has been setup as the compiler for ts-jest.
"^.+\\.ts$": ["ts-jest", { compiler: "ttypescript" }],

However, when ttypescript as compiler is removed from jest.config.js (which defaults to typescript instead), the tests mention no warnings. However, in my project I am having to use ts-auto-mock, which requires ttypescript to be used as the ts-jest compiler see here. I have also noticed this only seems to be happening on first run, unless jest cache is disabled.

I have created a barebones Vue3 project with ttypescript setup as ts-jest compiler here to demonstrate the warnings.

While looking into this, I also stumbled onto this discussion which seemed to point the same issue at ttypescript #Swatinem/rollup-plugin-dts#206.

The warning with stacktrace is as follows:

I get this on ttsc --watch with a generic custom transformer plugin

import * as ts from 'typescript';

export default function transformer() {
    return (_: ts.TransformationContext) => {
        return (source: ts.SourceFile) => {
            return source
        };
    };
}

Also added a barebones repo that can reproduce the issue:

If you change the transformer to javascript rather than typescript. it works with no errors
