Help needed to understand error message: Container failed to initialize, please ensure you are using the latest fdk and check the logs
Hi
I'm following your tutorial for hotwrap. Previously, I've followed it successfully. However, now I get an error message with: Container failed to initialize, please ensure you are using the latest fdk and check the logs:

What am i doing wrong?
I've attached my used Dockerfile and func.yaml files to this post as *.txt files: func.yaml.txt Dockerfile.txt
