If I try to run the script src/index.ts, it results in this error
TypeError [ERR_UNKNOWN_FILE_EXTENSION]: Unknown file extension ".ts" for /home/chen/development/relatrack-backend/src/index.ts
at Object.getFileProtocolModuleFormat [as file:] (node:internal/modules/esm/get_format:160:9)
at defaultGetFormat (node:internal/modules/esm/get_format:203:36)

at async MessagePort.handleMessage (node:internal/modules/esm/worker:196:18) {

But if I run the script with script/index.js, I get this error
node:internal/modules/cjs/loader:1147
throw err;

- Operating system and version: Ubuntu 23.10 x86_64
i have this issue as well :/ really frustrating only workaround i got is
node --no-warnings=ExperimentalWarning --loader ts-node/esm ./someDirectory/index.ts
FWIW - I ran into this issue just now and after banging my head against the wall for about 30 minutes, I realized the file I was calling fell under a pattern in my .gitignore file so it wasn't pulling into the build server I was running on. Dumb mistake on my part but my be an easy issue to overlook.
