                }
            }, {
                "type": "input",
                "element": {
                    "type": "plain_text_input"
                },
                "label": {
                    "type": "plain_text",
                    "text": "Label",
                    "emoji": true
                }
            }]
        }

这是我通过斜杠命令调用时遇到的错误。

failed with the error "invalid_blocks"

只是想知道从slash命令调用模态的正确用法是什么。

谢谢。
