The form inputs appear to be wanting an array of maps, not an array of strings. The “Array Value” field is for specifying the value of an attribute inside one of the maps. For example given the map below, you would put “id” in the Array Value field if you wanted the following inside the form: [“321”,“123”]
[
{
"id":"321",
"value":"temporary"
},
{
"id":"123",
"value":"string"
}
]
This is what I’m gathering after poking around for a bit, but please correct me if I’m wrong!
