Quick question: one of my colleagues reports that he has to run the typescript transpiler manually for his pulumi project. I fail to find what is missing from his setup why he has to do that. Does anyone know what “config” is used by Pulumi CLI to determine that the project is Typescript?

Has he turned off the built-in transpilation as described here? https://www.pulumi.com/docs/intro/languages/javascript/#disabling-built-in-typescript-support
