We have seen in Mistral (<span class="drupalorg-gitlab-issue-link project-issue-status-info project-issue-status-7"><a href="https://www.drupal.org/project/ai_provider_mistral/issues/3567467" title="Status: Closed (fixed)">#3567467: Mistral provider fails with Canvas AI when tool has no parameters</a></span>) that this fails whenever its empty.</p> <p>Because this will change for all providers, and we can't be 100% certain this doesn't cause BC. This is set to 2.0.x even if its a bug, more than a function.</p> <h3 id="summary-proposed-resolution">Proposed resolution</h3> <p>Add so the function always returns parameters with a json schema skeleton.</p>
