Add an Appsync Custom Resource with aws-amplify cli - amazon-dynamodb

Question

I'm trying to add a custom resource via amplify. I proceeded to add the resource in CustomResources.json but it gives me an error:
CustomResourcesjson AWS::CloudFormation::Stack UPDATE_FAILED Thu Nov 24 2022 13:18:36…
🛑 An error occurred during the push operation: /
Resource is not in the state stackUpdateComplete
I also used the amplify add custom command in AWSCloudformation format but it gave me another type of error.
My goal is to reproduce this procedure written for serverless, but on amplify:
- type: AMAZON_DYNAMODB
name: likeMutation
config:
tableName: !Ref LikesTable
iamRoleStatements:
- Effect: Allow
Action: dynamodb:PutItem
Resource: !GetAtt LikesTable.Arn
- Effect: Allow
Action: dynamodb:UpdateItem
Resource:
- !GetAtt UsersTable.Arn
- !GetAtt TweetsTable.Arn
It is about creating a data source connected to a table but whose permissions allow you to perform operations on other tables.
The resource I added in the CustomResources.js file is:
"LikeMutationDataSource": {
"Type": "AWS::AppSync::DataSource",
"Properties": {
"ApiId": "f353mqkxyzcgncck6xqbtdlboe",

"LikeMutationRoleMine"
]
},

}
}
},

}

}
Help me to implement this DataSource with amplify.
I've been looking for a solution for two days!
Thankyou all
