Set Value define schema as array not working

Wappler Version : 5.1.2
Operating System : MacOS
Server Model: NodeJS
Database Type: N/A
Hosting Type: Docker

Expected behavior

Set Value define schema allows to define the return as being an array

Actual behavior

Set Value schema is always set to object

Temporary workaround

Open the server action in Code View and manually set "outputType": "array"
