Estoy tratando de actualizar mi aplicación NodeJS12 & TypeScript a Node16, uno si el motivo es la necesidad de usar esperas de nivel superior.
El código se compila correctamente después de la actualización, pero Jest no aceptará el código de espera de nivel superior específico:
ts-jest[ts-compiler] (WARN) src/xxx.ts:11:17 - error TS1378: Top-level 'await' expressions are only allowed when the 'module' option is set to 'es2022', 'esnext', 'system', or 'nodenext', and the 'target' option is set to 'es2017' or higher. 11 const project = await client.getProjectId(); ~~~~~ FAIL src/xxx.test.ts ● Test suite failed to run Jest encountered an unexpected tokenpaquete.json:

Últimamente se me ocurrió que, que yo sepa, CJS no es compatible con la espera de nivel superior, lo que significa que debe usar ts-jest con esm.
mi jest.config.json

node --experimental-vm-modules -r tsconfig-paths/register -r ts-node/register node_modules/.bin/jest --runInBand --config jest.overall.json
