Logging

How to debug your extension

The Extension Host creates a log file which can contain useful information.

The log file can be found here:

  • Windows - \Users\[username]\AppData\Roaming\Ableton\Live x.x.x\Preferences\ExtensionHost.txt
  • Mac - /Users/[username]/Library/Preferences/Ableton/Live x.x.x/ExtensionHost.txt

The log file contains general information about the Extension Host, as well as the output of your extension’s console.{log|error|info|warn} calls. The stack trace of uncaught exceptions is also logged to this file.
