Error using "cdc_start_position" argument in the creating aws_dms_replication_task resource- terraform

Question

I am using Terraform v1.1.0 on Mac 64bit and aws terraform provider 3.7.0 to build AWS DMS components.

Here is the block to create DMS replication task -

resource "aws_dms_replication_task" "dms_repl_task_rev" {
  cdc_start_position        = "4AF/B00000D0"
  migration_type            = var.dms_migration_type
  replication_instance_arn  = aws_dms_replication_instance.dms_repl_instance.replication_instance_arn
  replication_task_id       = "dms-replication-task-id-rev"
  replication_task_settings = "..."
  source_endpoint_arn       = aws_dms_endpoint.pg_dms_source_ep.endpoint_arn
  table_mappings            = "..."

  tags = {
    Name = "dms-test"
  }

  target_endpoint_arn = aws_dms_endpoint.s3_dms_target_ep.endpoint_arn
}

cdc_start_position is a valid arg as per documentation https://registry.terraform.io/providers/hashicorp/aws/latest/docs/resources/dms_replication_task

However, I run into this error -

╷ │ Error: Unsupported argument │ │ on main.tf line 176, in resource "aws_dms_replication_task" "dms_repl_task_rev": │ 176: cdc_start_position = "4AF/B00000D0" │ │ An argument named "cdc_start_position" is not expected here. ╵

Has anyone used the parameter before. I believe my version should be supporting the parameters here.

Thank you.

The cdc_start_position was added in v3.62.0 of aws provider. Thus it seems you have older version and must upgrade .
