List indices must be integers, not slice while using json

Code:

@bot.command()
async def start(ctx):
    edit = []
    file = open("wallet.json", "r+")
    for line in file:
        temp = json.loads(line)
        edit.append(temp)

    userid = []
    for i in range(len(edit)):
        userid.append(edit[i]["id"])

    user = str(ctx.author.id)
    if userid.count(user) > 0:
        await ctx.reply("You already have an account")
    else:
        embed = nextcord.Embed(title = "Blablabla", description = "Blablabla")
        embed.set_footer(text = "Blablabla")
        await ctx.send(embed = embed)

        entry = {"id": user, "gold": 0, "fyre": 0, "faction": None}

    json.dump(entry, file)

Json: empty

Error:

userid.append(edit[i]["id"])
TypeError: list indices must be integers or slices, not str

Essentially, I'm trying to make a json file that adds an object every time this Discord command is ran. You can ignore everything with the words "Nextcord", "Embed", and "ctx" in them. When I run the command, the json gets an object inside an array. This causes my for loop that's adding stuff to the userid list to get a Typeerror, as it was designed to load a big jumble of objects, not arrays.

Inside wallet.json:

[{"id": "My Discord ID, in my real code it's there", "gold": 0, "fyre": 0, "faction": null}]

Another part of my code which does a similar thing worked flawlessly, so there must be something wrong with this piece of code. Please help.

The issue here is that you are loading the json wrong; and thus your userid list is empty. The below snippet populates your userid variable properly:

@bot.command()
async def start(ctx):
    file = open("wallet.json", "r+")
    edit = json.load(file)

    userid = [i["id"] for i in edit]

    user = str(ctx.author.id)
    if userid.count(user) > 0:
        await ctx.reply("You already have an account")
    else:
        embed = nextcord.Embed(title = "Blablabla", description = "Blablabla")
        embed.set_footer(text = "Blablabla")
        await ctx.send(embed = embed)

        entry = {"id": user, "gold": 0, "fyre": 0, "faction": None}

    json.dump(entry, file)
