I have tried enabling “S3BUCKETS” Services auto tag value using Entity selector, but it is not working properly. Getting attached error below. Please guide me on how&nbsp;to resolve this issue.

Hi&nbsp;[@manivarma](https://community.dynatrace.com/user/62929),

Unfortunately limited entitiy types can be use at auto-tags. I have not found a list about it. I also faced an issue eg. with the type of CLOUD\_APPLICATION\_INSTANCE.

Best regards,

János
