@tachev Did you have an existing (or did you add) a Dockerfile prior to debugging? If not, if you add a Dockerfile (e.g. using the task to scaffold the Docker assets), does debugging then work?

Based on the error, it looks like the Dockerfile was missing or not in the expected location. If that's the case, then we might just need to add a pre-debugging check that the Dockerfile exists before continuing forward.

I didn't have a Dockerfile before that. I expected this function will create one for me.

Phil - If you want to go that route, some of the commands will ask about adding a dockerfile:
