not able to use existing logging role

[droger88]

we would like to use an existing role for logging configuration because our permission setup, but when the attribute is set, it is still trying to create a new role
appsync configuration

appSync:
  name: demo-post-api
  logging:
    level: ALL
    retentionInDays: 14
    enabled: true
    roleArn: "arn:aws:iam::12345:role/appsync-datasource"
....

here is the output
