Where in the cloud function is this array or data meant to be? Is it from const query = new Moralis.Query("ItemsForSale") or are you talking about results?

#3

Hi Glad
sorry I’m talking about the results…
Cheers

#4

You can add some logging here with logger.info(JSON.stringify(NFTowners)) to see how the data looks like

#5

Hi cryptokid
Where do I put this logging,info?

#6

Just add it directly and then you can check the logs from your Moralis server’s dashboard.

const NFTowners = await Moralis.Web3API.token.getNFTOwners(options);
logger.info(JSON.stringify(NFTowners));

If you are not getting any data in the results variable, you can use logger.info at different places for different variables to see where your cloud function isn’t working properly.
