Recreating the Error

  1. Make a new portfolio
  2. Buy Stock with the portfolio
  3. Swap the stock and number of stocks to buy
  4. Click submit and get 500 error
  5. Return to previous page
  6. Buy stock correctly

When the steps above are recreated, the error message below generates. I'm currently unsure of what this would affect

Portfolio's log:
