Are you talking about this data?
uri throws an error: call to NFTContract.uri errored: Error encoding arguments: Error: invalid BigNumber string (argument=âvalueâ, value="", code=INVALID_ARGUMENT, version=bignumber/5.5.0)
For example, I opened mint and uri in them, you see what is written, what corresponds to uploading metadata like a book: https://eips.ethereum.org/EIPS/eip-1155#metadata
There is data on rinkeby.etherscan.io.
What to look for ?, how to fix my problem?: meta data is not displayed on Opensea
Next time can you please post links/addresses directly also so we donât have to type them in from your screenshots.
Using 0xc933d143777649018eb8226b188b47e0e1904008 as your contract, your metadata is broken for tokens 1 and 2 (3 doesnât have a valid token_uri link) as your double quotes are in the wrong places for some of the keys.
This is token_id 1:
{
"image:" "https://fmsamz8ufy99.usemoralis.com/picture2.png",
"description:" "Direct interaction of music on the appearance of a person and on his inner world",
"name:" "musical hairstyle",
"external_url": "https://feed-product.com"
}
It should be:
{
"image":"https://fmsamz8ufy99.usemoralis.com/picture2.png",
"description":"Direct interaction of music on the appearance of a person and on his inner world",
"name":"musical hairstyle",
"external_url":"https://feed-product.com"
}

Thanks, Iâve corrected the quotes. Recreated the contract. Problem still exists!
Help, what else could be wrong?

I tried to run your solidity code with my server url and it seems to be working and the images are loading at opensea.
But, when I try the same code with your server url the images are not loading at the opensea. 
Here is the code that I used with my server url. and my metadata0, metadata1

Maybe try another server. Everything looks fine now using your new contract for tokens 1 and 2. Keep in mind that the JSON link for token 3 is still broken.

Hi guys, the server was replaced, everything was rebuilt, the contract was generated, the result was not given. The meta data is not displayed.
https://rinkeby.etherscan.io/tx/0x9212ee14db8fd3dc41f0b8f5fc27848fbf57367a54dd9f973647e9ede64e7c0a
Any other ideas?
I get this metadata uri for token id 1:
https://iuql5ikmnexm.usemoralis.com/{id}.json
that points to this:
https://iuql5ikmnexm.usemoralis.com/0000000000000000000000000000000000000000000000000000000000000001.json
that has this metadata:
{
"image": "https://fmsamz8ufy99.usemoralis.com/picture2.png",
"description": "Direct interaction of music on the appearance of a person and on his inner world",
"name": "musical hairstyle",
"external_url": "http://feed-product.com"
}
and this link doesnât work: https://fmsamz8ufy99.usemoralis.com/picture2.png

I replaced the server as your colleague recommended. And now it works:
https://iwwqp0mjkfzw.usemoralis.com/
And this didnât work:
https://iwwqp0mjkfzw.usemoralis.com/apicture1.png
Replaced only the link of the server.
Any thoughts?
You have to upload that image on that server. Using moralis-admin-cli. Or you can use ipfs urls and upload the image to IPFS.

Links to the pictures work, the server is new, the code is checked, I created a new contract, but the metadata was not loaded on Opensea) it would not be as funny as it is insulting)!
What else to check?
https://rinkeby.etherscan.io/address/0x9ff2d7937812996faba87f0c13a72c1d6377ae14
Please post a link to instructions on how to download IPFS.
You also have to wait some time until opensea indexed that data.
For ipfs: https://docs.moralis.io/moralis-dapp/files/ipfs#saving-files
this one it looks like still has problems with not found

token_id 3 - token_uri doesnât load
Iâve noticed that https://iwwqp0mjkfzw.usemoralis.com/0000000000000000000000000000000000000000000000000000000000000000.json works which I assume is meant to be for token_id 1.
You need to correct all of these before things will work.
I rechecked everything, I used new pictures, everything works but is not displayed on Opensea

Not displayed on Opensea:
If I understand correctly, then Opensea does not collect meta data on the test domain. Correctly? And why?
If it updates the data in time: 1) at what time? 2) how many times a day?
Guys, take a look, tell me, thanks!
I have a rinkeby test contract on opensea an it displays fine.but I have found that it only works if I name the json files 1.json, 2.json, etc. They appear almost instantly.See below:
I donât understand why it works this way, and it doesnât work with 64 chars
Me neither but I tried it with 64 chars originally and it doesnât display on OpenSea!
