It tries to build a warning link with <code>$entity-&gt;getUntranslated()-&gt;toUrl('edit-form')</code>. Paragraphs don't have that link template.</p> <p>ParagraphTranslationHandler overrides entityFormAlter() but not entityFormSharedElements(), so the broken call still runs.</p> <h4 id="summary-steps-reproduce">Steps to reproduce</h4> <ol> <li>Make a paragraph bundle translatable with "hide non translatable fields" on.</li> <li>Add at least one untranslatable field.</li> <li>Create a node with this paragraph in the default language.</li> <li>Add a translation in another language.</li> <li>Open the Frontend Editing for the translated paragraph.</li> </ol> <p>The toUrl('edit-form') only runs when:</p> <ul> <li>editing a non-default translation</li> <li>bundle has default_translation_affected_only</li> <li>at least one untranslatable field gets hidden</li> </ul> <h3 id="summary-proposed-resolution">Proposed resolution</h3> <p>Override <code>entityFormSharedElements()</code> in <code>ParagraphTranslationHandler</code>. Same pattern as the existing <code>entityFormAlter()</code> override.</p> <p>When the entity has no edit-form link template, skip the link and show the warning text only.</p> <p><strong>Why no link?</strong><br> There is no good link target for a paragraph in this context:</p> <ul> <li>The standalone paragraphs_edit.edit_form is an admin route. Inside the Frontend Editing iframe it would render the full backend in the iframe.</li> <li>Linking to the root parent's edit form (the node) has the same problem: the full node edit form inside the iframe.</li> <li>Opening the link with target="_blank" pulls the user out of the editing flow into a new tab.</li> </ul> <p>The warning text alone is enough. The user can switch to the original language themselves.</p>
