Hey donjgo,
maybe. The best thing is to figure out what you have changed since the last time when it still worked. Maybe you’ve update or installed some libs, created new files, etc.
In my case it was a import statement within apollo-client which breaks meteor … To say it short: It was ES6 code which wasn’t compiled by the meteor build system as I violated the proper way in ‘apollo-client’ to import the stuff. So, for some reasons – I don’t know exactly why – the result was that the meteor build tool couldn’t build the files and transform the code from ES6 to ES5. That’s why the error function causes the error – it simply wasn’t transformed.
I can’t say where exactly the reason lies in your case, I could just mention my old case. 
Maybe it is caused through the package ostrio – have you installed it? Have you tested what happens, if you won’t use it – is the error still there then?
