This error isn’t related to ts-jest, the error indicates about something with ts-node. You should check with Jest community or search a bit more on google or debug to see what happened.

In general this error happens when you use Jest config in TypeScript which Jest uses ts-node to process that file.

ts-jest is code transformation which means it only executes on test files or files which are imported by test files, see more at https://jestjs.io/docs/code-transformation
