[Solved] 1.8.1 or 1.8 needs more tests

l am getting an error
TypeError: Cannot read property ‘constructor’ of undefined
for a non direct dependency on meteorhacks:meteorx

In my project l have this tree:

staringatlights:fast-render@2.16.5
├── accounts-base@1.4.3 (expanded above)
├── chuangbo:cookie@1.1.0
├── deps@1.0.12 (expanded above)
├── ejson@1.1.0 (expanded above)
├── livedata@1.0.18 (expanded above)
├─┬ meteorhacks:meteorx@1.4.1
│ ├── mongo@1.6.2 (top level)
│ └── random@1.1.0 (top level)
├── meteorhacks:picker@1.0.3 (expanded above)

I cannot find any solution to update meteorx nor break dependency with fast-render.
Any idea ?

Thanks

I ran into the same problem. lamhieu:meteorx actually fixes that problem so you probably need to update your version of staringatlights:fast-render

± meteor show staringatlights:fast-render  
Package: staringatlights:fast-render@3.0.8    
Maintainers: staringatlights                  
Git: https://github.com/abecks/meteor-fast-render
                                              
Fast Render is back!                          

Fast Render can improve the initial load time of your app, giving you 2-10 times faster initial page loads. It
provides the same effect as Server Side Rendering (SSR), but still sends data over the wire to avoid breaking one of
Meteor’s core principles.

Great. I was looking for a solution in that sense…
tnx.
