Why is 'undefined' returned when i make the following 'dasApi' request?

[freewillyjenkins]

import { createUmi } from '@metaplex-foundation/umi-bundle-defaults';
import { dasApi } from "@metaplex-foundation/digital-asset-standard-api";

const httpsEndpoint = https://maximum-magical-wave.solana-mainnet.quiknode.pro/${process.env.QUICKNODE_API_KEY}
const umi = createUmi(httpsEndpoint).use(dasApi())

const asset = await umi.rpc.call(
'getAsset',
[
'CgR9FHnrh16az7ztTCMnzdq4HjMmAZcx6dBRszgipump'
]
);
console.log(asset)

I tested the request with other token addresses and it works, but i don't know what it is about certain token addresses that return undefined
