Support for modern envs missing for canvas at 2.11

I was trying out some GitHub maintenance actions and it looks like the modern GitHub Action build env isn't compatible with the version of Canvas this npm library uses. If it is possible, it looks like an update to that package should solve some build issues in more recent environments.

Thank you for reporting. I'll be looking into this as soon as I can.
