Unstable or flaky website build: "Error from server (NotFound): the server could not find the requested resource"

The following build failed https://foundation.eclipse.org/ci/webdev/job/public/job/asciidoc-wg.eclipse.org/job/main/118/

The message seems to indicate a flaky (?) build

[Pipeline] withKubeConfig
[Pipeline] {
[Pipeline] sh
deployment "asciidoc-wg.eclipse.org" image updated
Error from server (NotFound): the server could not find the requested resource
Error from server (NotFound): the server could not find the requested resource
[Pipeline] }
[kubernetes-cli] kubectl configuration cleaned up
[Pipeline] // withKubeConfig
[Pipeline] }

As this is unrelated to the latest commit, and as it worked ~5 minutes before without a problem, I ask the Eclipse Web Dev team to assist / cc: @cguindon
