How can I create a branch from an Argo workflow?

问题

我正在尝试在Argo工作流中发送HTTP POST请求以在GitHub上创建一个分支。它一直失败，我无法弄清楚原因。看起来像是一些微小的问题，我会感激任何帮助来解决这个问题。

在执行过程中，我只看到一条消息 successCondition 'response.statusCode == 201' evaluated false。日志中没有看到任何信息。

以下是我的工作流程：

我期望在GitHub上创建一个分支。

I am trying to send a HTTP post request in Argo workflows to create a branch in GitHub. It keeps failing and I am not able to figure out why. It looks like something sticky and small, and I would appreciate any help in figuring this out.

While executing, I just see a message successCondition 'response.statusCode == 201' evaluated false. I don't see anything in logs.

I expect a branch to be created in GitHub.

以下是已翻译的内容：

"So silly of me to make this mistake."
很愚蠢的我犯了这个错误。

As per the official github documentation the ref in the request body should be like this "ref":"refs/heads/<branch-name>".
根据官方的GitHub文档，请求体中的ref应该像这样："ref":"refs/heads/<branch-name>"。
