Recently, we’ve been getting some strange errors during the Middleman build on our CI. For most files, we are seeing the error “pathname contains null byte”. The error does not happen on local builds and nothing has changed in our CI lately. Of course, we are looking to see if the issue is on our end but meanwhile, thought I’d throw this out there to see if anyone has any ideas or if this has affected others.
Here’s the full stack trace from one error’ed page. You can see that the Spanish (es) version builds just fine but then the Portuguese version fails with above error.
