Amazon Elastic Compute Cloud (EC2) is a web service that provides resizable compute capacity in the cloud. It is designed to make web-scale cloud computing easier for developers. EC2 allows you to launch virtual servers, known as instances, which can be used to run applications, store data, and perform a variety of tasks.
When working with EC2 instances, you may encounter the InvalidTag.NotFound error. This error typically occurs when you attempt to access or modify a tag that does not exist on the specified resource. Tags are key-value pairs used to organize and manage your AWS resources.
This error might appear during operations such as querying instances by tag, modifying tags, or using automation scripts that rely on specific tags.
The InvalidTag.NotFound error indicates that the tag you are trying to access or modify is not present on the resource. This could be due to a typo in the tag key or value, or the tag may have been removed or never existed.
Tags are used to categorize resources by assigning metadata to them. Each tag consists of a key and an optional value, both of which you define. For more information on tagging, refer to the AWS EC2 Tagging Documentation.
To resolve the InvalidTag.NotFound error, follow these steps:
Ensure that the tag key and value you are using are correct. Double-check for any typos or case sensitivity issues. You can list all tags for a resource using the AWS Management Console or AWS CLI.
aws ec2 describe-tags --filters "Name=resource-id,Values="
Confirm whether the tag has been removed. If the tag was deleted, you will need to recreate it. Use the following command to add a tag:
aws ec2 create-tags --resources --tags Key=,Value=
If you are using scripts or automation tools, ensure that they reference the correct tag keys and values. Update any hardcoded values that may be incorrect.
