松弛错误 : failed with the error "invalid_blocks"

Question

我正在构建一个启动模式的内部 Slack 应用程序，因此可以更有效地为技术请求提供票证。

当我在对斜杠命令的 JSON 响应中从我的 API 返回以下内容时，我收到错误失败并显示错误“invalid_blocks”，但是，当我将其放入 block-kit-builder 时，它运行良好(包括“发送到松弛”按钮)

知道为什么当我运行 slash 命令时会失败吗？是否可以从 slack 中看到更详细的错误消息？

当从 Slash 命令获取负载时，发送的响应只能返回一条消息。模式必须通过 views.open API 方法打开，将 JSON 传递给 view 参数，斜线命令有效负载中的 trigger_id ，以及用于验证您的请求的 token 。

使用 Bolt和 Block Builder JS 库，这看起来像这样:

const openMyView = async ({ body, context, client }) => {

  // Do some stuff and build viewParams object

  const view = callSomeMethod(viewParams); // Calls a method that uses Block Builder to build a modal

  await client.views.open({
    view: view.buildToJSON(); // Could also be just the JSON built from Slack's builder site
    token: context.botToken,
    trigger_id: body.trigger_id,
  });
};
