Troubleshooting tag changes - Tagging AWS Resources

Troubleshooting tag changes

The following checklist might be helpful if errors occur when you try to apply or change tags on selected resources in Find resources to tag query results.

  • The resource might already have the maximum number of tags. Generally, resources can have a maximum of 50 user-defined tags. AWS generated tags don't count toward the 50-tag maximum. Other users might also be adding tags to the same resource at the same time, which could raise the resource's tags to the maximum.

  • Some services allow a different character set (or restrict the character set that is allowed) for creating tags. If you added or changed tags using special characters, review the tag requirements in the resource's service documentation to verify that those characters are allowed by the service.

  • You might not have permissions to modify the tags for the resource. If you don't have permissions to view existing tags on a resource, you can't make changes to the resource's tags.

  • You might not have permissions to change the resource. Changes to the resource's metadata might be restricted by another administrator.

  • The resource might have been edited or deleted by another user or process. For example, assume that a resource was launched as part of the creation of an AWS CloudFormation stack. If the stack was deleted or is no longer in an active state, the resource might no longer be available.

  • Tag changes might not be possible if a resource is offline or terminated, or if other updates (such as software upgrades) to the resource are in progress.

  • Tag changes can fail if you close the browser tab or change the page before the tag changes complete. Let tag changes finish, and wait for the success or failure banner to appear on the page, before you leave the page.

  • While there's a rate limit for the AWS Resource Groups Tagging API, the service you're tagging might impose a separate limit which you might hit before the Resource Groups Tagging API limit.
