Azure RM Template. Conditinally deploy Copy resource

I need to deploy specific resource if there are more than 4 entries in an array parameter. I'm able to do this with 5 (and more) entries, but I also need the deployment not to fail with 3 or less entries, but rather not create that resource at all. Right now I get the following error with 3 or less entries:

Error: Code=InvalidTemplate; Message=Deployment template validation failed: 'The template 'copy' definition at line '56' and column '19' has an invalid copy count. The copy count must be a positive integer value and cannot exceed '800'. Please see https://aka.ms/arm-copy for usage details.'.

I tried adding condition to the resource:

...
  "resources": [
    {
      "condition": "[greater(length(parameters('apps')),4)]",
      "name": "[concat(parameters('apps')[copyIndex(4)].name,'-webtest')]",
...

and even:

...
  "resources": [
    {
      "condition": false,
      "name": "[concat(parameters('apps')[copyIndex(4)].name,'-webtest')]",
...

but still getting the same error. This is the template:

try doing it like so:

"condition": "[greater(length(parameters('apps')),4)]",

and set you copy to this:

"copy": {
  "name": "createWebTests",
  "count": "[if(greater(length(parameters('apps')),4), sub(length(parameters('apps')),4), 1)]"
}

this should work around the fact that in your case count is negative and still not deploy anything when there are less than 4 items in your array
