Hi, I'm stuck with an error message, when trying to build a docker image. After it didn't work with my custom Dockerfile, I tried with the example from the pulumi repo (https://github.com/pulumi/pulumi-docker/tree/master/examples/dockerfile-py), but with no luck either. This is the error message I'm seeing:

error: Program failed with an unhandled exception:

I can't make much of the output. Maybe you have an idea?

it looks like the issue is it can't find the

Dockerfile

, did you try setting it explicitly?
