在传递CommaDelimitedList类型的参数值时看到AWS CLI Cloudformation错误 [英] Aws cli cloudformation error seen on passing parameter value of type CommaDelimitedList

问题描述

我看到了CommaDelimitedList参数值的无效类型错误。 CF可以从控制台正常运行。

I am seeing an invalid-type error for a CommaDelimitedList parameter value. The CF runs without any errors from the console.

AWS CLI命令：

AWS CLI command:

aws cloudformation create-stack --stack-name agkTestUserStack --template-body file://api_user.yaml --parameters ParameterKey=CustomUserName,ParameterValue="svc_TestUser" ParameterKey=GroupAssociations,ParameterValue="Dev,Test"

输出：

Parameter validation failed:
Invalid type for parameter Parameters[1].ParameterValue, value: [u'Dev', u'Test'], type: <type 'list'>, valid types: <type 'basestring'>

推荐答案

默认情况下，aws cli将逗号分隔的值用作List，因此您需要使用 \来转义逗号。 字符。请按照以下步骤重试。

By default, aws cli takes comma seperated value as List, hence you need to escape commas by using \ character. Please retry as per below.

aws cloudformation create-stack --stack-name agkTestUserStack --template-body file://api_user.yaml --parameters ParameterKey=CustomUserName,ParameterValue="svc_TestUser" ParameterKey=GroupAssociations,ParameterValue="Dev\,Test"
