I am also having an issue with this -LiteralPath error. Were you able to resolve it, or does anyone have any advice?
I found my cause, an invalid log path defined in the AppDeployToolkitConfig.xml.

No have not resolve it. Use execute-process as work around for now. It really strange cause it worked before.
