<p>I recently installed <strong>FluxCD 1.19.0</strong> on an <strong>Azure AKS</strong> k8s cluster using <strong>fluxctl install</strong>. We use a private git (<strong>self hosted bitbucket</strong>) which Flux is able to reach and check out. </p>

<p>Now Flux is not applying anything with the error message:</p>

<p>From what I understand, Flux passes the resource definitions to kubectl, which then applies them? </p>

<p>The way I interpret the error would mean that kubectl isn't passed anything to. However I opened a shell in the container and made sure Flux was in fact checking something out - which it did. </p>

<p>I tried raising the verbosity to 9, but it didn't return anything that I deemed relevant (detailed outputs of the http requests and responses against the Kubernetes API).</p>

<p>So what is happening here? </p>

<p>The problem was with the version of kubectl used in the 1.19 flux release, so I fixed it by using a prerelease: <a href="https://hub.docker.com/r/fluxcd/flux-prerelease/tags" rel="nofollow noreferrer">https://hub.docker.com/r/fluxcd/flux-prerelease/tags</a></p>
