Thank you @Wardrium for the report and @unlight for looking into it. I'm working on a fix.

[chuanqisun]

done! 2.1.0 release should get this patched. Let me know if you still see any errors after the update.

Thank you!

I also noticed michael-silva forked the library and fixed the issue with a slightly different approach. Kudos to the community!

That fork should prevent the ts compiler error but didn't address the root cause. If someone actually uses a symbol as the property name, the test will break. My fix added the error checking and warning message when symbols are used.
