InvalidArgumentValue: --subnet: Invalid format

### Describe the bug

I'm trying to create a private endpoint by using Azure CLI in bash terminal.
First, I read ASK subnet id by the command

```
akssubnet=$(az network vnet list --query "[?contains(id, 'aks-orgname-dev')].subnets[0].id" -o tsv)
echo $akssubnet
/subscriptions/xxxxxxxx-110f-42cf-8f82-xxxxxxxxxxb0/resourceGroups/MC_compute_aks-orgname-dev_westeurope/providers/Microsoft.Network/virtualNetworks/aks-vnet-33919582/subnets/aks-subnet
```

then I use this variable in the command
```
az network private-endpoint create \
-g MC_compute_aks-orgname-dev_westeurope \
-n postgresql-private-endpoint-orgname-dev \
--group-id postgresqlServer \
--subnet "$akssubnet" \
--nic-name postgresql-private-endpoint-orgname-dev-nic \
--private-connection-resource-id "$postgresqlid" \
--connection-name postgresql-private-endpoint-orgname-dev
```
this returns me the error
```
InvalidArgumentValue: --subnet: Invalid format: resource id should be in '/subscriptions/{subscription}/resourceGroups/{resource_group}/providers/Microsoft.Network/virtualNetworks/{vnet_name}/subnets/{}' format.
```
but as you can see above, the `$akssubnet` has exactly this format
