Serverconnect formatter not working on api-returned data

Hi all,

I have attached the server action file (uses public api sample data) for the below bug report.

Details

1. I have an public api that returns a dataset which is an array of objects

2. The api data is assigned to variable array_of_objects1, output is printed

3. The api data is also put through a repeat and the two properties of each object is printed

The output of both steps 2 & 3 are exactly the same:

[{
	"name": "dept1",
	"staff": "john"
}, {
	"name": "dept1",
	"staff": "jack"
}, {
	"name": "dept2",
	"staff": "joe"
}, {
	"name": "dept3",
	"staff": "jim"
}]

.
In the last two steps, I tried using the groupBy formatter on the above two “array of objects”:

4. When the groupBy is tried on the variable array_of_objects1 that holds the api data, I’m getting the following error:

5. When the groupBy is tried on the repeat array_of_objects2 that outputs the same data, the group by seems to work just fine. The output prints correctly as ["dept1","dept2","dept3"]

It’s exactly the same data, while the groupBy formatter works on a repeat output (step-3, which is my current workaround), its not working directly on api returned data (expected & ideal).

Also, not sure if this issue is only with the groupBy formatter not working on api-returned “array of objects”.
