This topic provides troubleshooting advice for common errors and issues that you might encounter while implementing ABAC in DynamoDB tables or indexes.
Service-specific condition keys aren't considered as valid condition keys. If you've used such keys in your policies, these will result in an error. To fix this issue, you must replace the service-specific condition keys with an appropriate condition key to implement ABAC in DynamoDB.
For example, say that you've used the dynamodb:ResourceTag condition key in an inline policy that performs the PutItem request. Imagine that the request fails with an AccessDeniedException. The following example shows the erroneous inline policy with the dynamodb:ResourceTag condition key.
{
"Version": "2012-10-17",
"Statement": [
{
"Effect": "Allow",
"Action": [
"dynamodb:PutItem"
],
"Resource": "arn:aws:dynamodb:*:*:table/*",
"Condition": {
"StringEquals": {
"dynamodb:ResourceTag/Owner": "John"
}
}
}
]
}To fix this issue, replace the dynamodb:ResourceTag condition key with aws:ResourceTag, as shown in the following example.
{
"Version": "2012-10-17",
"Statement": [
{
"Effect": "Allow",
"Action": [
"dynamodb:PutItem"
],
"Resource": "arn:aws:dynamodb:*:*:table/*",
"Condition": {
"StringEquals": {
"aws:ResourceTag/Owner": "John"
}
}
}
]
}If ABAC was enabled for your account through Support, you won't be able to opt out of ABAC through the DynamoDB console. To opt out, contact Support
You can opt out of ABAC yourself only if the following are true:
-
You used the self-service way of opting in through the DynamoDB console.
-
You're opting out within seven calendar days of opting in.
