• 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.

Expected Behavior

• Kendra index is created
• Kendra FAQ is created and associated with the Kendra index created above.

Actual Behavior

• Kendra index is created
• Kendra FAQ is created and associated with the Kendra index created above.
• Kendra FAQ is in failed status and Terraform shows the below error message.

[! IMPORTANT]
awscc_kendra_index.example is created as part of the process here.

• On re-applying or re-planning, the Terraform plan identifies changes in the Kendra index and attempts to destroy/recreate and is stuck.
  • Note that there was no change done in the Kendra index configuration between the FAQ failure and re-apply

Plan: 2 to add, 2 to change, 2 to destroy.

Steps to Reproduce

1. terraform apply
2. Review the failure and perform another terraform apply with the changes to original failed FAQ ( CSV to CSV_CSV_WITH_HEADER)

This is happening with kendra_data_source as well.

Steps to reproduce:

1. Create a Kendra index and Kendra datasource ( custom)
2. Comment the datasource and re-apply.
3. Apply is forcing a replacement of the index which shouldn't be part of this operation.

Terraform used the selected providers to generate the following execution plan. Resource actions are
indicated with the following symbols:
  ~ update in-place
  - destroy
-/+ destroy and then create replacement

Terraform will perform the following actions:

I believe the problem with Kendra FAQ is upstream AWS.

awscc_kendra_faq.example: Creating...
awscc_kendra_faq.example: Still creating... [10s elapsed]

thanks for reporting this, we'll investigate this separately.

@quixoticmonk ,

Could you please share your Terraform state file for resource awscc_kendra_index.example , attribute name: server_side_encryption_configuration. I suspect that you found it shown as null in the Terraform state file.

[wellsiau-aws]

likely relates to #1139

[quixoticmonk]

It is.

On my recent test with provider AWSCC 1.2.0 , I saw that the behavior has changed a bit.

Terraform plan is no longer triggering replacement, I believe thanks to the fix on #1712, however it still detecting drift

  # awscc_kendra_index.example will be updated in-place
  ~ resource "awscc_kendra_index" "example" {
      + capacity_units                       = (known after apply)
        id                                   = "7f069663-4368-44fd-8ac4-745dd11cf43e"
        name                                 = "example-index"
      + server_side_encryption_configuration = (known after apply)
        tags                                 = [
            {
                key   = "Modified By"
                value = "AWSCC"
            },
        ]
      + user_token_configurations            = (known after apply)
        # (7 unchanged attributes hidden)
    }

Debug log is telling interesting story:

Attribute in question: document_metadata_configurations

[wellsiau-aws]

The remaining problem in this issue is now more relevant to problem discussed in #1216.

@quixoticmonk , the original issue (force replacement) has been resolved, I would like to continue the discussion on the remaining issue at #1795 to keep the discussion separate. As such, I am going to go ahead and close this issue.
