expected token 'Identifier' and actual 'LeftSquareBracket' in Arm Template when parsing if statment

I'm trying to set a variable in the variables section of an ARM template using the if function. in the parameter section I've definded a parameter that is been filled by a parameter file. let's call it condition:

"condition": {
  "type": "bool",
  "defaultValue": false}

now in the variables section I would like to define a variable that if condition is true then var = ["1","2","3"] else var = [] an empty array.

I've tried:

"var" : "[if(parameters('condition'),[\"1\",\"2\",\"3\"],[])]"
"var" : "[if(parameters('condition'),['1','2','3'],[])]"
"var" : "[if(parameters('condition'),array(['1','2','3']),array([]))]"

all with the same result expected token 'Identifier' and actual 'LeftSquareBracket' error thrown.

of course I can solve it in a similar way to:

"var0" : ["1","2","3"],
"var1" : [],
"var" : "[if(parameters('condition'),variables('var0'),variables('var1')]"

but that would lead to two dummy variables and an uglier code, and I would really like to avoid it.

trying to deploy from azure CLI.

It is surly a syntax error but I just can't figure it out.

Thanks in advance for your help!

Well, Turn's out the answer is just to use the built-in json() function.

I've solved it with:

"var" : "[if(parameters('condition'),json('[\"1\",\"2\",\"3\"]'),json('[]'))]"
