pset8 finance check50 fails on "checking that "56.00" is in page" even though it is in the page

Question

My sell function redirects to index, and I am able to see the correct stock prices and total value amounts formatted as USD, but for some reason check50 won't pass me on the final test (https://cs50.me/checks/f7c356884025daa03aebbe91edd59db9cafc4c27)

As suggested by the approved answer in pset7 finance check50 doesn't detect a valid sale despite portfolio updating correctly, I tried adding the following lines to lookup():

if symbol == "AAAA":
    return {"name": "Test A", "price": 28.00, "symbol": "AAAA"}

After doing this, I created a new account, bought 4 shares of 'AAAA', and sold 2 of them. As expected, index displayed $56.00 worth of shares and a cash balance of $9,944.00. So, I'm perplexed as to why I'm still failing check50. I also tried the suggestion of removing indexes from my database, but to no avail.

Update: Solved (see curiouswiki's answer)

Answer 1

After reviewing your actual code

/sell needs to accept a POST request where shares is a number of shares, and symbol is a stock symbol. Your code has /sell take symbol as the ID of a row in a table called symbols

So that’s throwing things off. check50 is sending a payload like {"shares": 2, "symbol": "AAAA"}, but you are asking for something like {"shares": 2, "symbol": 28}
