在k8s执行演练报错getClient: k8s exec failed, err: an empty namespace may not be set when a resource name is provided

[wenjunGU]

k8s版本为1.18.3，无论新建任何演练都会报同一个错误，演练参数中的namespace确认填写无误。{
"response": {
"code": 63061,
"error": "{7e6b64493e583371 %!!(MISSING)s(bool=false) getClient: k8s exec failed, err: an empty namespace may not be set when a resource name is provided [{7e6b64493e583371 Error %!!(MISSING)s(int32=0) getClient: k8s exec failed, err: an empty namespace may not be set when a resource name is provided %!!(MISSING)s(bool=false) }]}: k8s exec failed, err: getClient%!!(MISSING)(EXTRA *errors.errorString=an empty namespace may not be set when a resource name is provided)",
"success": false
}
}
请问这是个什么BUG？
