json - 选择状态不指向下一个状态 - AWS

Question

我有以下步进功能。执行在选择状态下失败。

"States": {
    "Process": {
        "Type": "Task",
        "Resource": "arn:aws:lambda:us-east-1:123:function:dummy1",
        "OutputPath": "$",
        "Next": "ChoiceStatePre"
    },

    "ChoiceStatePre": {
        "Type": "Choice",
        "Choices": [{
            "Variable": "$.status_pre",
            "Next": "Series0",
            "NumericEquals": 1
        }, {
            "Variable": "$.status_pre",
            "Next": "MatchStatePre",
            "NumericEquals": 8
        }]
    },
    "MatchStatePre": {
        "Type": "Task",
        "Next": "PreProcess",
        "Resource": "arn:aws:states:us-east-1:123:activity:dummy2"
    },
    "Series0": {
        "Resource": "arn:aws:lambda:us-east-1:123:function:dummy3",
        "Type": "Task",
        "InputPath": "$.seq0.step0",
        "ResultPath": "$.seq0.step0",
        "OutputPath": "$",
        "Next": "ChoiceStateTrigger0"
    }
}

错误 -

{
"error": "States.Runtime",
"cause": "An error occurred while executing the state 'ChoiceStatePre' 
(entered at the event id #7). Failed to transition out of the state. The 
state does not point to a next state."
}

我已经有了它的下一个状态，但是错误表明选择状态没有指向任何下一个状态。

在查看“ChoiceStatePre”时，我没有看到默认状态。这似乎是这次失败的根本原因。请添加默认状态并重试。像这样的东西：

"DefaultState": { "Type": "Fail", "Cause": "No Matches!" }
