No I cannot. It is super simple. Please upgrade Jest to "^28.1.0" and see this link for upgrading from 27 to 28.

https://jestjs.io/docs/upgrading-to-jest28

You have to add code: ... see

Transformer[​](https://jestjs.io/docs/upgrading-to-jest28#transformer)

process() and processAsync() methods of a custom [transformer module](https://jestjs.io/docs/code-transformation) cannot return a string anymore. They must always return an object:

  process(sourceText, sourcePath, options) {
-   return `module.exports = ${JSON.stringify(path.basename(sourcePath))};`;
+   return {
+     code: `module.exports = ${JSON.stringify(path.basename(sourcePath))};`,
+   };
  }
