Impossible to fill a repeatable textstring through API

[raymondvisser1977]

Put
https://api.umbraco.io/content/....id

Request
"uSPs":{
"$invariant": ["item 1","item 2","item 3","item 4"]
},

returns:
"uSPs": {
"$invariant": []
},

Along other properties that work perfectly fine.
The model is also being saved btw but it just wont fill the usps property

I tried several formats like :

I think this was answered through support, but just posting here as we haven't replied here through the tracker (and sorry about that 🙈 ),.

Format of a repeatable string should be

"uSPs":{
"$invariant": [{ "value": "test" }, { "value": "test2" }]
},
