The error you received is rather straightforward; a numpy array doesn't have a to_list method.

Instead you should simply iterate over the numpy array:

This issue was due to kubelet certificate expired and fixed following these steps. If someone faces this issue, make sure /var/lib/kubelet/pki/kubelet-client-current.pem certificate and key values are base64 encoded when placing on /etc/kubernetes/kubelet.conf

After lots of frustration it became apparent that the problem was once again in front of the computer. The following option in my git config was the culprit:

The host values of 0.0.0.0 for your connector configurations in hornetq-configuration.xml are invalid. This is why the broker logs:

You've forwarded the wrong port

9093 on the host needs to map to the localhost:9093 advertised port

Otherwise, you're connecting to 9093, which returns kafka:9092, as explained in the blog. Container hostnames cannot be resolved by the host, by default

You need to set correctly rest.advertised.host.name (or CONNECT_REST_ADVERTISED_HOST_NAME, if you’re using Docker). This is how a Connect worker communicates with other workers in the cluster.

For more details see Common mistakes made when configuring multiple Kafka Connect workers by Robin Moffatt.

In your case try to remove CONNECT_REST_ADVERTISED_HOST_NAME=localhost from compose file.

Codecov has some heisenberg issues. If you don't have a token, please add one otherwise try to:

• Force-push to retrigger Codecov
• Rotate your token.

This is not an official solution. I'm sure the rbenv devs are working on an actual solution but this workaround should help others who are setting up their ruby environments on the new M1 chips for Mac.

• Make sure your Terminal is using Rosetta. You can find how to do that using Google.

• Uninstall your current rbenv following these instructions Removing rbenv. Be sure you also remove all the downloaded versions of ruby if you have any (minus the system default) located in /Users//.rbenv/versions/.

• Uninstall the ARM version of Homebrew with: /bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/uninstall.sh)"

• Install the x86_64 version of Homebrew with: arch -x86_64 /bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install.sh)"

• If you run brew install rbenv should produce output saying "Error: Cannot install in Homebrew on ARM processor in Intel default prefix (/usr/local)!". This is expected.

• You want to tell brew to install the older architecture x86_64 arch -x86_64 brew install rbenv

• Then finally install the version you want using arch -x86_64 rbenv install x.x.x (x = some number i.e. 2.7.2)

From there you just need to remember to tell brew arch -x86_64 when installing other versions of Ruby.

Once an actual fix comes through you'll be able to switch back to the newer architecture and not have to use the arch argument. You also don't have to do this all the time with brew either, just rbenv.
