@pleerock np, I made a simpler repro and the problem didn’t exist. What was happening is I had an old .js file in the target directory.

rm -rf dist/* && tsc

solved it…annoying problem, but has to do with tsc not typeorm. the problem happens when you create/delete/rename .ts files.

For people who come here with the same problem, that solved for me. I’ve deleted the ‘dist’ folder and ran npm run build.

After that, it worked again.
