Calling nft metadat via cloud function

Technical Issue Reporting
#21

@cryptokid, following up on the above. i am getting currently below output by using .then(res => console.log(res)):

Response {type: 'cors', url: 'https://feciihxhdokr.usemoralis.com:2053/server/fu…=ePc0HyzXQdJ3ytVt8J4zhNDWS0WCFSANX6z87xIC&nftId=0', redirected: false, status: 200, ok: true, …}

[[Prototype]]: Response

now, I would like to parse the body. i tried the below, but i am getting always empty results back. any idea how to fix? let me know if you need further information:

            //.then(res => res.json())
            //.then(res => JSON.parse(res.result))

here is the log:

How do you call that getNFT function?
What do you see in your browser console, any errors there?

#24

Can you add some logging before that return?
It looks like this cloud function doesn’t return anything

no errors if i am calling getNFT function. I am receiving below output in my console:

Response {type: 'cors', url: 'https://feciihxhdokr.usemoralis.com:2053/server/fu…=ePc0HyzXQdJ3ytVt8J4zhNDWS0WCFSANX6z87xIC&nftId=1', redirected: false, status: 200, ok: true, …}
#27

What does that error line from logs means?

#28

not sure. below is my cloud function:

Moralis.Cloud.define("getNFT", async (request) => {

    const logger = Moralis.Cloud.getLogger()


    let NFTId = request.params.nftId;
    let hexId = parseInt(NFTId).toString(16);
    let paddedHex = ("0000000000000000000000000000000000000000000000000000000000000000" + hexId).slice(-64)
    logger.info(paddedHex);
    return Moralis.Cloud.httpRequest({
      "url": `${"https://feciihxhdokr.usemoralis.com/" + paddedHex + ".json" }`,
      "headers": {
            'method': 'GET',
            'accept': 'application/json'
            }})
      .then(function(httpResponse){
      return httpResponse.data;
        },function(httpResponse){
        logger.info("error");
        logger.info(httpResponse);
        });
  });

perhpas it is complaing because i have multiple mints in my opensea account? below the link to my opensea account:
https://testnets.opensea.io/0x1b64bc818e06a21ca94c1d918d81e0615fe3073e

You can add here a line with: logger.info(JSON.stringify(httpResponse))

It looks like a 404 not found error, like when the url doesn’t exist.

#32

mhh, ok. but i don’t understand what is missing here? e.g. below URL is working if entered manually in the browser. any idea how to fix?

#33

You could log to see what is the exact url that is trying to access.

#34

i printed below url for my first nft. if entered manually in the browser, it returned empty.

https://feciihxhdokr.usemoralis.com:2053/server/functions/getNFT?_ApplicationId=ePc0HyzXQdJ3ytVt8J4zhNDWS0WCFSANX6z87xIC&nftId=0
#35

so the only solution would be to create a new server, new test account and try it again?

#36

No, I mean in your cloud function, to log what url is trying to access with that http request.

#37

ok, can you please help me by providing a snip of code? i am bit confused how to do it.

#38

You compute this url before using it in that function and you use logger.info(url) to see what you have there
