exception not being handled properly "Unexpected token '.'"

[t-900-a]

Relevant line of code in this package - https://github.com/NaturalSelectionLabs/RSS3-SDK-for-JavaScript/blob/6ea4dd5d28c0264abc3633550a0dda0c06f1fac2/src/files.ts#L60 Error received - "Unexpected token '.'" Error can be seen in full here - https://github.com/t-900-a/action-push-rss3/runs/5268971189?check_suite_focus=true

Code that is using this package - https://github.com/t-900-a/action-push-rss3/blob/main/src/rss3-push.js

The code that is being ran is using the private key who's public key pair is 0x76c9e9E2ca07c194a8f1E11C557fB26558D3336b

This public key is not registered, so I imagine that is what is causing the exception in the first place. This should be handled more gracefully.

node 12 doesn't support optional chaining. Error fixed by moving to node 16. https://github.com/t-900-a/action-push-rss3/runs/5277409107?check_suite_focus=true
