New-OCIPsqlDbSystem - Fail to create

I'm attempting to script the creation of new PostgreSQL systems but running into issues. The request seems to be accepted by the API and a work request is created but they end up failing to create. Creating Postgres via the OCI console with the same settings works correctly so I believe I am passing something in the request that is causing the behavior. I opened an OCI SR to look at the creation error but was hoping to have you validate that I am using this module correctly.

Below is a slimmed down version of the code being used with comments showing what is present in each object.

$PGCreateDbObj = New-Object -TypeName Oci.PsqlService.Models.CreateDbSystemDetails
    $PGCreateDbObj.DisplayName = 'TestPostgres' 
    $PGCreateDbObj.Description = 'TestPostgres Description'
    $PGCreateDbObj.CompartmentId = 'ocid1.compartment.oc1..aaaREDACTED'
    $PGCreateDbObj.SystemType = 'OCIOPTIMIZEDSTORAGE' 
    $PGCreateDbObj.DbVersion = '14'
    $PGCreateDbObj.Shape = 'PostgreSQL.VM.Standard.E4.Flex.2.32GB'    
    $PGCreateDbObj.InstanceCount = '2' 

    $PGStorageDetailsObj = New-Object -TypeName Oci.PsqlService.Models.OciOptimizedStorageDetails
    $PgStorageDetailsObj.IsRegionallyDurable = 'true' 
    $PGStorageDetailsObj.Iops = '300000'
    $PGCreateDbObj.StorageDetails = $PGStorageDetailsObj

    $PGCredentialsObj = New-Object -TypeName Oci.PsqlService.Models.Credentials
    $PGCredentialsObj.Username = 'PostgresAdmin' 
    $PGVaultSecretObj = New-Object -TypeName Oci.PsqlService.Models.VaultSecretPasswordDetails
    $PGVaultSecretObj.SecretId = 'ocid1.vaultsecret.oc1.iad.amaaaREDACTED'
    $PGVaultSecretObj.SecretVersion = '1'
    $PGCredentialsObj.PasswordDetails = $PGVaultSecretObj  
    $PGCreateDbObj.Credentials = $PGCredentialsObj

    $PGNetworkDetailsObj = New-Object -TypeName Oci.PsqlService.Models.NetworkDetails
    $PGNetworkDetailsObj.SubnetID = 'ocid1.subnet.oc1.iad.aaaREDACTED' 
    $PGCreateDbObj.NetworkDetails = $PGNetworkDetailsObj

    $PGMgmtPolicyDetObj = New-Object -TypeName Oci.PsqlService.Models.ManagementPolicyDetails
    $PGMgmtPolicyDetObj.MaintenanceWindowStart ='SUN 01:00' 

    $PGBackupDailyPolicyObj = New-Object -TypeName Oci.PsqlService.Models.DailyBackupPolicy
    $PGBackupDailyPolicyObj.BackupStart = '00:00'
    $PGBackupDailyPolicyObj.RetentionDays = '14'
    $PGMgmtPolicyDetObj.BackupPolicy = $PGBackupDailyPolicyObj
    $PGCreateDbObj.ManagementPolicy = $PGMgmtPolicyDetObj
