Expected Behavior

All drg attachments within the same compartment should be in the output.

Actual Behavior

Only vcn attachments were fetched.

Steps to Reproduce

1. Place the compartment ID as input for the data block oci_core_drg_attachments.
2. terraform init
3. terraform apply

Important Notes

We tried using oci cli to get all drg attachments using this command:
oci network drg get-all-drg-attachments --drg-id ocid1.drg.oc1.iad.<remaining_char_for_id_here>
https://docs.oracle.com/en-us/iaas/tools/oci-cli/3.51.4/oci_cli_docs/cmdref/network/drg/get-all-drg-attachments.html
The output includes all attachments in the included drg id.
