tsickle: Cannot read property 'toJSON' of undefined

I have a project here that uses ngc. However, when I compile the project using TS 2.2.2 and the command ./node_modules/.bin/ngc -p src/lib/tsconfig.json I get the following error…

TypeError: Cannot read property 'toJSON' of undefined

I would expect that this is probably related to using TS 2.2
