<p>The first question is, why is this method (even the whole class) called at all? As we want to edit a paragraph_block field, it seems <strong>highly</strong> unwanted to create any paragraph_block entity.<br>
So a proper solution would be to avoid that.</p>
<p>For a quick solution, another way is to ensure that no null values can be passed to the create() method, which in my case avoids this error.</p>
