App engine versions

I use Google App Engine for me nodejs project. Today I tried deploy the new version, but app engine throw error. After that I tried deploy the previous version (worked in past), steel throw error.

I do not understand it. It worked before, but now doesn't. The new version of App Engine? Could you help me please?

In log I see problem with lwip library. After remove it works, but I need the library.
