500 error message rails heroku

Question

I get an error when saving records or having a POST or DELETE request to my db on Heroku. This is my first time deploying a rails app on heroku and I don't know what can be causing the issue. I have also searched online and read the logs but still no sign of cause. The strange thing is the record gets saved but it shows me a 500 message.

Delete method:

def destroy if @contact.destroy flash[:success] = "Successfully deleted contact" redirect_to root_path else flash[:warning] = "Problem encountered while deleting the current contact." end end

Log:

Answer 1

The solution was to add the elasticsearch addon provided by heroku and re-migrated the database. Thanks everyone :)
