Expecting 'CONTENT', 'COMMENT', 'OPEN_BLOCK'.... error

[WisdomCorp]

Hello guys,

I am getting above error when I am running the TypescriptEntityGen\tsgen.js -i metadata.json command.

Any specific typescript or handlebar.js version is required. This was working fine before few months.

breeze.client: ^1.5.5
handlerbars: ^1.3.0 (as mentioned in package.json)
