When I returned back to the book I haven't started writing the log right away.

I kinda finished a couple chapters and I am on the chapter ELM and API data and I want to fetch the players list. I can fetch the games list, it works fine. I can't fetch players list even though I don't have any raised exceptions.
Everything seemed to work fine, when in fact only the half works fine.
Bijan told me in email, when I asked him, a debugging technique. And here is the message that I got in the console:
Error fetching players from APIBadBody "Problem with the value at json.data[0].score:\n\n null\n\nExpecting an INT": ({ gamesList = [], playersList = [] },)
As you cane see the score has a null value.
On to the next chapter "Design and Usability".
mix phx.routes
allows you to see the list of all routes in your app.

Didn't have any issues at all. Was a smooth ride.

11:35 Just finished the "Our First Game" chapter.
I just had one idea in my mind. In this game we will have only one coin at a time. How can I set the game up for multiple coins at the same time?

So far, the feedback that I get from Elm is super staight forward.

09:57 Starting to read "Phoenix Channels and Elm Ports"
There will likely be a time in the near future where packages make it simple for developers to
integrate the two languages with a straightforward API, but currently it can be a tedious process to
connect things properly.
The good news is that this knowledge is valuable, because any non-trivial Elm application is likely
going to need to work with JavaScript code and knowing how to use ports is essential.
I like the reassuring tone of the book.
Isn't this awesome?
We’re going to use Phoenix channels for a similar purpose. We’re going to take the playerScore
field that we’re tracking in our Elm application, and we’re going to broadcast that value to other
users so all players can see scores for a particular game being tracked in real-time. We’ll also take a
look at how to store the scores as records in our database using the gameplays table we configured
earlier in the book
