I guess it is caused by some response which doesn't contain `header` field in its body. You can take your investigation from: https://github.com/api7/lua-resty-etcd/blob/f2abd8b99629c1c8b133aa25e6c7c20a255d0d4a/lib/resty/etcd/v3.lua#L90 You can search corresponding response or just dump them out. The patch below may help you catch those response: ```diff diff --git apisix/core/etcd.lua apisix/core/etcd.lua index 07af2b06..a26b4958 100644 --- apisix/core/etcd.lua +++ apisix/core/etcd.lua @@ -89,6 +89,9 @@ function _M.get_format(res, real_key, is_dir) return nil, "insufficient credentials code: 401" end + if not res.body.header then + local cjson = require("cjson.safe"); ngx.log(ngx.ALERT, "", cjson.encode(res.body)) + end res.headers["X-Etcd-Index"] = res.body.header.revision if not res.body.kvs then ``` ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
