Not working out of the box

One has to use the following command:
aws cloudformation deploy --template-file /Users/nmas409/aws-sam-java-rest/aws-sam-java-rest/packaged.yaml --stack-name sam-orderHandler --capabilities CAPABILITY_IAM
Waiting for changeset to be created..

But getting this error.

Failed to create the changeset: Waiter ChangeSetCreateComplete failed: Waiter encountered a terminal failure state Status: FAILED. Reason: [/Resources/DeleteOrderFunction/Type/Environment/Variables/TABLE_NAME] 'null' values are not allowed in templates

This doesn't work at all:
sam deploy \
--template-file packaged.yaml \
--stack-name sam-orderHandler \
--capabilities CAPABILITY_IAM

首先检查 packaged.yaml，特别是 DeleteOrderFunction 的 Environment Variables 中的 TABLE_NAME 条目，然后比较文档中记录的 aws cloudformation deploy 和 sam deploy 命令。重现部署失败，并验证示例在没有 null 的 TABLE_NAME 值时能够成功部署。
