我有一个调用python lambda函数的codestar项目 . 此函数尝试将项目放入DynamoDB . 我收到以下错误：
"errorMessage": "An error occurred (AccessDeniedException) when calling the PutItem operation: User: arn:aws:sts::13556632xxxx:assumed-role/CodeStar-split-lambda-Execution/awscodestar-split-lambda-lambda-CreateUser-RBA73BJH7NHY is not authorized to perform: dynamodb:PutItem on resource: arn:aws:dynamodb:us-east-1:1355663xxxx:table/split-users" }
我在 CodeStar-split-lambda-Execution 角色中包含了 AmazonDynamoDBFullAccess ， AWSLambdaBasicExecutionRole 和 AWSLambdaInvocation-DynamoDB 策略，但我仍然收到错误 .
我也制定了自己的政策并尝试过 .
{
"Version": "2012-10-17",
"Statement": [
{
"Sid": "VisualEditor0",
"Effect": "Allow",
"Action": [
"dynamodb:*"
],
"Resource": [
"arn:aws:dynamodb:us-east-1:13556632xxxx:table/split-users"
]
}
]
}
如何让dynamoDB获得放置物品的授权？
