<p>I am trying to create custom resource definition in kubernetes using kubernetes python client, but i am unable to do so, it would be helpful if someone can explain what i am doing wrong here</p>

<p><strong>Anything else we need to know?</strong>:</p>
<p><strong>Environment</strong>:</p>
<ul>
<li>Kubernetes version (<code>v1.18.6</code>):</li>
<li>OS (ubuntu 20.04):</li>
<li>Python version (<code>3.8.2</code>)</li>
<li>Python client version (<code>11.0.0</code>)</li>
</ul>

<p>Let's take a look at the error message:</p>
<blockquote>
<p>CustomResourceDefinition in version &quot;v1beta1&quot; cannot be handled as a CustomResourceDefinition: v1beta1.CustomResourceDefinition.ObjectMeta: v1.ObjectMeta.Labels: CreationTimestamp: unmarshalerDecoder: parsing time &quot;null&quot; as &quot;2006-01-02T15:04:05Z07:00&quot;: cannot parse &quot;null&quot; as &quot;2006&quot;</p>
</blockquote>
<p>So, as the error message suggests, there is a problem with <code>CreationTimeStamp</code>. Now the question is, what's wrong with your <code>CreationTimestamp</code>?</p>
<p>Your CreationTimestamp should be:</p>
<pre><code>{
&quot;creationTimestamp&quot;:null, // creationTimestamp is actually defined, but the value is null
}
</code></pre>
<p>instead of:</p>
<pre><code>{
&quot;creationTimestamp&quot;:&quot;null&quot;, // setting creationTimestamp equal to a string value &quot;null&quot;
}
</code></pre>
