Did anyone had any timezone issues while running flow, with a docker storage, which was built using a custom Dockerfile? (This is ran on Kubernetes, via Kubernetes Agent) I get the following error, while running a flow:

RuntimeError: Unable to find any timezone configuration

Add the following to your dockerfile:

ENV DEBIAN_FRONTEND=noninteractive
RUN apt-get update -y && apt-get install -y tzdata

It will set the timezone to UTC

Thanks a lot, that works! 🙌
