The generateContent endpoint called from \Drupal\ai_provider_google_vertex\Plugin\AiProvider\VertexProvider::chat is returning
Please use a valid role: user, model.
I tracked it down to the line: 'role' => ($message->getRole() === 'assistant') ? 'model' : $message->getRole() as one of my messages has the role tool.
Additionally, finding the real error was very difficult thanks to code like \Drupal\ai_provider_google_vertex\Plugin\AiProvider\VertexProvider::throwError which rather than just throwing Unknown Error: Could not get a response from the model this should throw a more obvious error to help debugging
