                  No template for interactive request TodoItemsController#new is missing a template for request formats: text\/html NOTE! Unless told otherwise, Rails expects an action to render a template with the same name, contained in a folder named after its controller. If this controller is an API responding with 204 (No Content), which does not require a template, then this error will occur when trying to access it via browser, since we expect an HTML template to be rendered for such requests. If that’s the case, carry on. ChatGPT<\/p>\n\n\n\n
