Restoring RDS Snapshot with CloudFormation

Question

I am trying to recreate an RDS Aurora database from a snapshot using CloudFormation and I am running into a problem. During the stack creation, I am getting this error 'Only DB Snapshot Identifiers can be used with the filter DB_SNAPSHOT_ID'

Here is a snippet of my CF template:

Parameters:
      DBSnapshot: 
         Type : "String"
         Default: "arn:aws:rds:us-west-2:893352710245:cluster-snapshot:snapshot"

Resources:
      RDSDatabase:
         Type: "AWS::RDS::DBInstance"
         Properties:
           DBInstanceClass: 'db.t2.micro'
           DBSnapshotIdentifier: !Ref DBSnapshot

Accepted Answer

Think I found the issue:

DBSnapshot:
         Type : "String"
         Default: "arn:aws:rds:eu-west-1:300688157164:cluster-snapshot:snapshot"
    
    Resources:
      MyDB:
        Type: "AWS::RDS::DBCluster"
        Properties:
          SnapshotIdentifier: !Ref DBSnapshot
          Engine: "aurora"

You are restoring a cluster so need to use AWS::RDS::DBCluster and SnapshotIdentifier and not the AWS::RDS::DBInstance.
