limit-req 的rejected_msg 不起作用，有人知道是为啥吗

[ztf219]

在路由里加上了limit-req，但rejected_msg没起作用

"plugins": {
        "limit-req": {
            "rate": 1,
            "burst": 0,
            "rejected_code": 503,
            "key": "remote_addr",
            "rejected_msg": "aoh, too many, tmd!!!"
        }
    },

What's the version of your APISIX?

2.6

Please upgrade your APISIX version, the rejected_msg was released since 2.9.
