<h3 id="summary-problem-motivation">Problem/Motivation</h3>
<p>I have a multilanguage site setup, with different node types and quite some Paragraphs.<br>
I am experiencing different errors on different environments, when trying to use ai_translate to translate existing content pages.</p>
<p>Some of the errors:</p>
<ul>
<li><code>Error attempting rollback of 695e2cb91bd944.76982807\savepoint_6. Active stack: 695e2cb8bccd70.27699708\drupal_transaction</code></li>
<li><code>round(): Argument #1 ($num) must be of type int|float, string given</code> - triggered on a DecimalItem field type</li>
</ul>
<p>While these seem to be site-specific issues, they disappear when I roll back the change in <span class="drupalorg-gitlab-issue-link project-issue-status-info project-issue-status-7"><a href="https://www.drupal.org/project/ai/issues/3482645" title="Status: Closed (fixed)">#3482645: AI Translate Module Leaves Fields Empty When No Translation is Found</a></span>.<br>
At that point, the translation works as expected (and no data seems to be missing for which <span class="drupalorg-gitlab-issue-link project-issue-status-info project-issue-status-7"><a href="https://www.drupal.org/project/ai/issues/3482645" title="Status: Closed (fixed)">#3482645: AI Translate Module Leaves Fields Empty When No Translation is Found</a></span> was introduced).</p>
<h4 id="summary-steps-reproduce">Steps to reproduce</h4>
<p>I can't quite put my finger on the exact cause of this issue yet, so not sure how to recreate the circumstances in which this happens. I'm mostly creating this issue for when I could pinpoint the exact reason / circumstances for this behaviour.</p>
