Hi all,
I just successfully deployed my application, however I am unable to run the rails:db seed with the command flyctl ssh console -C ‘/app/bin/rails db:seed’.
it return this error :
flyctl ssh console -C ‘/app/bin/rails db:seed’
Connecting to … … complete
fork/exec /app/bin/rails: no such file or directory
Can someone help me resolve this issue? thanks
