Hi,
What data do you have in ItemsForSale table?

#3

4 nft items

#4

Ok, in this case you have a typo: itemsForSale vs ItemsForSale

#5

just resolved this but nothing is fetched still…

#6 
query = new Moralis.Query("itemsForSale");
x = await query.find()

returns those 4 items for me
You can try to debug to see where is the problem, by checking if it returns what it should return, if it returns then if it is properly displayed.

#7

I wrote a separate function to recall the cloud function for get items on sale but still nothing yet. meaning the fault is from the cloud function and i cant still pinpoint the error. i tried this your example too but nothing yet

#8

You could try to remove some of the filtering that is done in that cloud function until in returns something.

#9

@kasodon, from my tests if doesn’t pass this line if (!queryResults[i].attributes.token || !queryResults[i].attributes.user) continue;, but this may be because I can not query with masterkey.
Do you have user and token fields in ItemsForSale table?

#10

specifically no, but there is tokenid and rest

#11

It looks like that function will not return anything if user and token fields are not present in that table, because it specifically checks for those fields presence and then it tries to get info from those fields.

#12

yeah true, rechecking it

#13

SOLVED!!! :blush:All i did was just to update and restart server :man_dancing:

#14

@cryptokid can you point me on deploying these to other testnet chains like polygon and bsc? Please… :pray:

#15

It depends on what tool you use for deploy. Most of the time you have to change the deployment network and to use an address that has enough funds to make the deploy.

#16

okay great, but since its testnet, i can always get enough funds to deploy, like on bsc testnet. I’m right though?

#17

you are right, you can get enough funds on bsc testnet from a faucet
