Not Support

Error message

Not Support

What it means

TrayIconItem's file dialog is configured for single selection; if the dialog somehow returns an array (multiple selections), the code throws 'Not Support' because multi-select tray icons are not implemented.

Solutions

1. Select exactly one file in the dialog
2. Pick a single png/jpg/jpeg/bmp/ico file when choosing a custom tray icon
3. If it persists, reset the tray icon setting to default

if (Array.isArray(selected)) {
  showToast('Please select a single icon file')
  return
}

const isSingleFile = (v: unknown): v is string => typeof v === 'string'

try {
  await pickTrayIcon()
} catch (e) {
  if (e instanceof Error && e.message === 'Not Support') {
    showToast('Multi-select is not supported for tray icons')
  }
}

When it happens

Trigger: Selecting a tray icon file when the dialog result is an array — occurs when the picker is invoked in a way that permits multiple selection or a platform quirk returns a list.

Common situations: Users on platforms/dialog implementations that return arrays from the open dialog trying to set a custom tray icon.

Understand the failure class

Background: UnsupportedOperationException and "is not supported" errors: when a library deliberately refuses a call — this error's family across 30 libraries.
