This isn't supported, but the Tamper-trait in eca_tamper still provides one because it's relying on the "handle_multiples" annotation-property of the underlying Tamper-plugin. See <a href="https://git.drupalcode.org/project/eca_tamper/-/blob/1.0.x/src/Plugin/TamperTrait.php?ref_type=heads#L135">https://git.drupalcode.org/project/eca_tamper/-/blob/1.0.x/src/Plugin/TamperTrait.php?ref_type=heads#L135</a>.</p> <h4 id="summary-steps-reproduce">Steps to reproduce</h4> <p>Use the attached model to replicate the error.</p> <h3 id="summary-proposed-resolution">Proposed resolution</h3> <p>Refactor the usage of "handle_multiples" OR create separate Tamper-Actions for the Encode-plugin (so not via the deriver)</p> > Related issue: [Issue #3391096](https://www.drupal.org/node/3391096)
