• The resources and data sources in this provider are generated from the CloudFormation schema, so they can only support the actions that the underlying schema supports. For this reason submitted bugs should be limited to defects in the generation and runtime code of the provider. Customizing behavior of the resource, or noting a gap in behavior are not valid bugs and should be submitted as enhancements to AWS via the CloudFormation Open Coverage Roadmap.

Panic Output

no

Expected Behavior

Having first deployed these 2 resources in the accounts, awscc_iot_domain_configuration and awscc_iot_ca_certificate, and then I want to update the tag values associated with them, the resources should update only those values, as do most of the other terraform resources.

Actual Behavior

An error appears saying that they cannot be updated. After a troubleshooting, what should be done is to do a taint of these resources, so that they are first deleted and recreated with the new tag values.

Steps to Reproduce

1. Deploy resources, terraform apply
2. Edit the tag values in the terraform files
3. Try to deploy these changes again, terraform apply

Important Factoids

Nothing special, these resources are general resources for the account, one that controls the custom domain and another that registers the certified domain in IoT. Nothing particular that has to do with this problem
