• 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.

Terraform CLI and Terraform AWS Cloud Control Provider Version

Terraform v1.2.6 on darwin_amd64

Debug Output

Panic Output

Expected Behavior

State refreshed in reasonable time (I believe in under 1m for a couple of resources), no excessive CPU usage

Actual Behavior

State of awscc_lex_bot is being refreshed in several minutes with CPU utilisation of awscc-terraform-provider process of 150%

Steps to Reproduce

1. terraform plan

I can now see the same behaviour when refreshing state of awscc_connect_phone_number

[gevial]

Also noticed that after Terraform showed this: Plan: 1 to add, 0 to change, 0 to destroy. it didn't release the console input back and CPU utilisation was still 150%. I think it would time out, but I just entered Yes without a prompt and it proceeds with creating.
