Upgrading jest from 26.6.3 to 27.0.0 is a major version upgrade that introduces breaking changes. The current ts-jest version (26.4.4) is not compatible with jest 27.x. According to ts-jest's compatibility matrix, jest 27.x requires ts-jest 27.x. This incompatibility will cause the tests to fail.

Consider upgrading ts-jest to version 27.x (e.g., "ts-jest": "^27.0.0") to ensure compatibility with jest 27.0.0.
