Program Error With Alchemist Recorded Code

Photoshop UXP Plugin API
1

I have recorded some steps with Alchemist but when I run it from the Plugin, I get a message box saying… “Could not complete your request because of a program error”

I have since run the code direct from Alchemist Play button and it seems to run ok.

I am using MAC with latest Photoshop

Any one got any suggestions please

  const batchPlay = require("photoshop").action.batchPlay;
  const result = await batchPlay(
  [
     {
        "_obj": "set",
        "_target": [
           {
              "_ref": "channel",
              "_property": "selection"
           }
        ],
        "to": {
           "_ref": "channel",
           "_enum": "channel",
           "_value": "RGB"
        },
        "_isCommand": true,
        "_options": {
           "dialogOptions": "dontDisplay"
        }
     },
     {
        "_obj": "duplicate",
        "_target": [
           {
              "_ref": "channel",
              "_property": "selection"
           }
        ],
        "_isCommand": true,
        "_options": {
           "dialogOptions": "dontDisplay"
        }
     },
     {
        "_obj": "select",
        "_target": [
           {
              "_ref": "channel",
              "_name": "Alpha 1"
           }
        ],
        "_isCommand": true,
        "_options": {
           "dialogOptions": "dontDisplay"
        }
     },
     {
        "_obj": "set",
        "_target": [
           {
              "_ref": "channel",
              "_enum": "ordinal",
              "_value": "targetEnum"
           }
        ],
        "to": {
           "_obj": "channel",
           "name": "Lighter Areas"
        },
        "_isCommand": true,
        "_options": {
           "dialogOptions": "dontDisplay"
        }
     }
  ],{
     "synchronousExecution": false,
     "modalBehavior": "fail"
  });

You have 4 actions in one batchPlay.
2 of those won’t work if channel with that name does not exist.

Sorry, I understand what you mean now, thanks
