Output filter with exclude on server workflow repeat generates error

Wappler Version : 4.8.1
Operating System : mac
Server Model: node
Database Type: maria

Expected behavior

If Exclude is selected for the output of a server side repeat, it should not error

Actual behavior

{
  "status": "500",
  "message": "props is not defined",
  "stack": "ReferenceError: props is not defined\n    at App.repeat (/Users/pauka/WapplerProjects/cf/lib/modules/core.js:56:60)\n    at App._exec (/Users/pauka/WapplerProjects/cf/lib/core/app.js:487:57)\n    at App._exec (/Users/pauka/WapplerProjects/cf/lib/core/app.js:458:28)\n    at processTicksAndRejections (internal/process/task_queues.js:93:5)\n    at async App.exec (/Users/pauka/WapplerProjects/cf/lib/core/app.js:427:9)\n    at async App.define (/Users/pauka/WapplerProjects/cf/lib/core/app.js:417:9)"
