Now we will get the correct Pokemon

We will create another function - this one will use the SetID as well as our CardNo

//Fetch Data
async function fetchData() {
    try {
        SetID = await checkDupes()
        data3 = await tcgdex.fetch('sets', SetID, CardNo) 

Again we will use an async function with a try statement
To get to our Pokemon we will get this from the TCGdex by searching in sets with our SetID - remember this was sv03 or sv03.5 there are a bunch of others. The CardNo was already given by the user an now we will finally bring it to use.

With this we will receive a complete info of the card which will look something like this

{
  "category": "Pokémon",
  "id": "sv04-113",
  "image": "https://assets.tcgdex.net/de/sv/sv04/113",
  "localId": "113",

      "effect": "Du kannst beliebig viele Karten aus deiner Hand auf deinen Ablagestapel legen, bis du 4 oder weniger hast. Ziehe so lange Karten, bis du 5 Karten auf deiner Hand hast."
    },
    {

      ],
      "name": "Verstärkte Klinge",
      "effect": "Wenn an dieses Pokémon 1 Pokémon-Ausrüstung angelegt ist, fügt diese Attacke 60 Schadenspunkte mehr zu.",

    }
  ],
  "retreat": 1,
  "regulationMark": "G",
  "legal": {
    "standard": false,
    "expanded": false
  }
}

As with every other thing in programming we need to catch any error in this use-case it could be one of the following

• CardNo ist not in the specified set
• Set is not filed in TCGDex - can happen with brand new Sets
• Set does not exist (we should be covering this in the function before)

In any case this will lead to a undefined variable data3

        //Check if we Card is already in TCGdex        
        if (data3 !== undefined) {
            //Get Pokemon Name
            PokeName = data3.name
            //Get Rarity of Card
            rarity = data3.rarity
            //Get SetID
            SetID = data3.set.id
            //Get Set Name
            SetID_Name = data3.set.name
            //Inform User
            console.log(`Set ID ist ${textColor}${SetID}${resetColor}`)
            console.log(`Set Name ist ${textColor}${SetID_Name}${resetColor}`)
            console.log(`Unser Pokemon ist ${textColor}${PokeName}${resetColor}`)
            console.log(`Unser Pokemon ist ${textColor}${rarity}${resetColor}`)

            return data3
        //Return Error if Set does NOT contain DATA
        } else {
            console.log(SetID,'ist leider nicht befüllt')
        } 
    } catch (error) {
        console.error('Error fetching sets:', error);
        return null;
    }}

We are using the if statement to check that data3 is defined - actually is NOT undefined
Afterwards we will use some of the data of the JSON to write back in to the console.
We are using

• Pokemon Name
• The rarity
• Which SetID we have (the stand sv03or in the above mentioned JSON sv04
• The Set Name - which will give the correct name of the set used

All these values we will print out to the console and return the complete JSON in data3to the next function
