I have a container running Debian.  Open Project was working well.  The only thing I can think of is I did an upgrade 'apt upgrade' and now openproject does not work openproject-web-1.service: Failed with result 'exit-code'.

I have tried openproject configure and I can see this error 

/opt/openproject/vendor/ruby-3.1.2/lib/ruby/3.1.0/rubygems/user_interaction.rb:621:in `initialize': Permission denied @ rb_sysopen - /dev/null (Errno::EACCES)

nothing online gives me any indication of what to do.  can anyone help me understand this ?

ok so I got this working by chmod 777 on /dev/null

Why did I have to do this?
