Azure resource can't find dependancy when deploying - azure

Question

I'm trying to deploy an Azure Windows VM using templates and keep running into the error code: InvalidResourceReference Resource X referenced by Resource Y was not found. Resource X is Microsoft.Network/networkSecurityGroups (named 'FBI') and resource Y is Microsoft.Network/networkInterfaces (named vInterface).
All my required resources are created during this deployment with their dependencies set in the template. The first thing I did was confirm that my FBI resource exists, which it did:
Next I ensured that my FBI security group was listed as a dependency in vInterface to ensure that FBI does get created first before vInterface is created, which it is:
{
"name": "[parameters('networkInterfaceName')]",
"type": "Microsoft.Network/networkInterfaces",
"apiVersion": "2018-04-01",
"location": "[parameters('location')]",
"dependsOn": [
"[resourceId('Microsoft.Network/publicIPAddresses', parameters('publicIpAddressName'))]",
"[resourceId('Microsoft.Network/networkSecurityGroups', parameters('networkSecurityGroupName'))]"
],
"properties": {
"ipConfigurations": [
{
"name": "ipconfig1",
"properties": {
"subnet": {
"id": "[variables('subnetRef')]"
},
"privateIPAllocationMethod": "Dynamic",
"publicIpAddress": {
"id": "[resourceId('VMGroup','Microsoft.Network/publicIpAddresses', parameters('publicIpAddressName'))]"
}
}
}
],
"networkSecurityGroup": {
"id": "[resourceId('VMGroup', 'Microsoft.Network/networkSecurityGroups', parameters('networkSecurityGroupName'))]"
}
}
}
I can confirm that the location is the same for both of these resources. Everything looks ok but I can't figure out why my vInterface can't find/see my FBI security group.
For reference here's the full error message:
"error": {
"code": "InvalidResourceReference",
"message": "Resource /subscriptions/---/resourceGroups/VMGroup/providers/Microsoft.Network/networkSecurityGroups/FBI referenced by resource /subscriptions/---/resourceGroups/VMDeployment/providers/Microsoft.Network/networkInterfaces/vInterface was not found. Please make sure that the referenced resource exists, and that both resources are in the same region.",

You are probably deploying to a resource group not called vmgroup hence this error.
your resource id's are hardcoded to vmgroup resource group, not to the resource group you are deploying to; change your resourceId() input to:
"[resourceId('Microsoft.Network/networkSecurityGroups', parameters('networkSecurityGroupName'))]"
ps. you have it in 2 places.
