Trying to make a robloxsearch command with RBLX Api

Question

I am trying to use ROBLOX's API to make a ;rs command but it isn't going so well.

Using request-promise I tried searching and it brought me this error:

SyntaxError: Unexpected token o in JSON at position 1

I have reviewed questions on here before and answered some. If this helps, I am using discord.js-commando for my command handler.

Here is the part the error is coming from:

let editMsg = await msgObject.reply(
  ":triumph: Finding ROBLOX Account, give me a second!"
);
let rs = await request({
    uri: `https://users.roblox.com/v1/users/search?keyword=${idk}&limit=10`,
    simple: false,
    json: true
});


if (rs.userFacingMessage == "Something went wrong"){
    if(rs.code == 5){
        editMsg.edit("Sorry 😣, We couldn't process your search! The username you provided has been filtered!");
    }
    if(rs.code == 6){
        editMsg.edit("Sorry 😣, We couldn't process your search! The username you provided is too short!");
    }
}else {
    let user = JSON.parse(rs)
    msgObject.reply(user)
}

Here is a PasteBin link if you need to see the whole run() method.

request-promise with the option json: true automatically parses the JSON string in the response. It means your variable rs is already an object, not a JSON string.

The JSON.parse() method parses a JSON string, so when you try to parse an object, Node.js converts it to a string first ([object Object]). The first character is [ which is valid JSON, but the second one (the letter o) is not, so you receive a SyntaxError: Unexpected token o in JSON at position 1.

Try it out below:

const rs = {
  previousPageCursor: null
}
try {
  console.log(JSON.parse(rs))
} catch (error) {
  console.log(error.message)
}

The API endpoint at https://users.roblox.com/v1/users/search?keyword=${idk}&limit=10 returns an object, so you can't simply send it as-is in a reply. You can use JSON.stringify() to create a string from that object, or you can get an array of users from rs.data.

If you want to return a single user, you can either grab the first item (rs.data[0]) from that array, or use the find() method to find one that matches your keyword:

} else {
  const user = rs.data[0]
  msgObject.reply(`\`\`\`${JSON.stringify(user, null, 2)}\`\`\``)
}

} else {
  const user = rs.data.find((u) => u.name === idk)
  msgObject.reply(`\`\`\`${JSON.stringify(user, null, 2)}\`\`\``)
}
