Repeat on Exec action returns Empty List in Exclude/Include field options

Wappler Version :4.9.1 and Beta 5.6
Operating System : Windows 11
Server Model: Node JS
Database Type: MariaDB
Hosting Type: Docker

Repeating the output of an exec action should return a list of fields as it does with other actions.

What actually happens?

The repeat returns an empty list, output is enables for the exec action.

I’ve tried in 4.9.1 and 5 beta 6, both show the same.
