I'm trying to create an ARM template which deploys a VM to a specified zone, however I keep getting the following error. Not sure why, I've checked online and followed the other examples, but still stuck.
The code for the zone template
"zone": {
"type": "string",
"defaultValue": "1",
"allowedValues": [
"1",
"2",
"3"
],
"metadata": {
"description": "Zone number for the virtual machine"
}
},
The Parameter file is:
"zone": {
"value": "2"
},
But the error I get is:
New-AzResourceGroupDeployment : 10:11:08 - Error: Code=InvalidTemplate; Message=Deployment template parse failed: 'Error converting value "2" to type 'System.String[]'.
Path ''.'.
At line:7 char:1
Can anyone point me in the right direction. I have tried using the zone as an array and integer, but neither seem to work.
Thanks in advance :)

The error message The language expression property array index '1' is out of bounds. is a bit misleading. After my validation. The main problem is using "copy" in dataDisks property there.
When you define the parameter diskCount number as 2, you should also define 2 matching elements in the parameter diskSize array. Also, I change to define the paramater zone type to string type.
Here is the working sample:
