Did you solve this error?

I know that I do not have this problem now, but without knowing what I was fighting with, I can't remember what the solution was. Did you follow a link here? If I can see where I linked it I can probably remember.

This is a dokku deploy log from an old project. The only thing that comes to mind immediately is: because I work in Windows, at one point my binstubs in the repo were not executable, so when they got to the server they wouldn't run.

I added the following to my dockerfile to make sure that doesn't happen in the future.

# make sure that binstubs are executable
RUN chmod u+x bin/*
