Error message

No script code available to edit. Please ensure you have a script open in the editor.

What it means

The AI edit-code tool applies LLM-produced diffs to the script currently open in the editor. scriptOptions holds that code; when it is undefined (no script/flow editor context), the tool throws this error and reports 'No script found in current context' in the tool status.

Solutions

1. Open the target script in the script editor before asking the AI to edit it
2. Verify the chat session is the one attached to the open editor (editor-scoped chat)
3. Reload the editor page if the script is visibly open but context was lost
4. Copy the code into the prompt or use a flow-scoped chat if editing within a flow step

Example fix

// before (global chat) — 'edit my script' -> throws
// after
// open /scripts/run/my_script, then ask in that page's chat
'fix the error in this script'

if (!scriptOptions || typeof scriptOptions.code !== 'string') {
  // no script open: ask the user to open the script editor first
}

function hasScriptContext(scriptOptions) {
  return scriptOptions != null && typeof scriptOptions.code === 'string'
}

When it happens

Trigger: Calling editCodeTool from a chat with no script open — global chat on the home page, a chat on a non-editor page, or the editor lost its script binding (e.g. after navigation).

Common situations: Asking the copilot to 'fix my script' from the dashboard; script editor still loading when the tool runs; chat session disconnected from the editor context.
