<p>When this error appears</p>
<p></p>
<p>If this error occurs intermittently when retrieving records or tables, the connection character encoding might not be correct.</p>
<p></p>
<p><span style="text-decoration: line-through;">If you are connecting with utf8, try switching to utf8mb4 and see if that resolves the issue.</span></p>

<p><a href="https://www.ytyng.com/blog/mysql-80-client-django-character-set-latin1-utf8mb4/">When connecting to a MySQL 5.7 server with a MySQL 8.0 client, the Charset cannot be specified from the client</a></p>
<p>As mentioned in the above link, when the MySQL client is version 8.0 and the server is version 5.7, the character encoding cannot be specified from the client-side.</p>
<p>Therefore, regarding character encoding, it is best to specify it on the server-side and <strong>not specify it from the client-side</strong></p>
<p>(do not specify <strong>OPTIONS in the DATABASES</strong>).</p>
