Why Token URI cannot find the Token Id?

kasra · December 26, 2022, 1:30pm

hello , I get this error after I minted a Token :
Value Error: execution reverted: ERC721Metadata: URI query for nonexistent token: ‘(‘ERC721Metadata: URI query for nonexistent token’,)’

and the command is :

def main():

    print("Working on " + network.show_active())

    advanced_collectible = getMultiDataTypeTemplate[len(getMultiDataTypeTemplate) - 1]

    number_of_NFT = advanced_collectible.TokenId()

    print(advanced_collectible.address)

   # print(advanced_collectible.tokenURI(TokenId))

    print(

        "The number of tokens you've deployed is: "

        + str(number_of_NFT)

         

    )

    for TokenId in range(number_of_NFT):

        breed = get_breed(advanced_collectible.TokenId())

        print(breed)

        print(advanced_collectible.tokenURI(TokenId))

        if not advanced_collectible.tokenURI(TokenId).startswith("https://"):

          print("Setting tokenURI of {}".format(TokenId))

you usually get this error when that token ids doesn’t exist, maybe you have to wait some time if you just minted that token id

okay when I run this :
def main():

  print("Working on " + network.show_active())

    advanced_collectible = getMultiDataTypeTemplate[len(getMultiDataTypeTemplate) - 1]

    number_of_NFT = advanced_collectible.TokenId()

    print(advanced_collectible.address)

   # print(advanced_collectible.tokenURI(TokenId))

    print(

        "The number of tokens you've deployed is: "

        + str(number_of_NFT)

I get this output :

The number of tokens you’ve deployed is: 1

so If it did not minted how it recognized I already minted a Token ? it would be my pleasure if you clarify this , thanks

you can see here how to post code on forum:

kasra · August 18, 2022, 3:26pm

I changed the type , now is it okay to read ?

cryptokid · August 18, 2022, 3:28pm

yes, it is better now, you have to know the exact token id that was minted, can you find it in a block explorer?

kasra · August 18, 2022, 3:33pm

yes , take a look at these pictures please :

cryptokid · August 18, 2022, 3:54pm

I don’t see the token id in those images

kasra · August 18, 2022, 4:00pm

its the TokenID in the right that shows TokenID : 1

is it true ?

cryptokid · August 18, 2022, 4:02pm

yes, that look like a token id

kasra · August 18, 2022, 4:04pm

so where is the problem in your opinion ?
I used tokenURI(unint256 tokenId) in my contract instead of using _setTokenURI … do you think it’s the problem or not ?

cryptokid · August 18, 2022, 4:06pm

try to print the TokenId here to see if if has the value that you expect

kasra · August 18, 2022, 4:13pm

it shows 0 for print(TokenId)
but it show 1 for print(number_of_NFT) that is number_of_NFT = advanced_collectible.TokenId()

cryptokid · August 18, 2022, 4:23pm

You are using somewhere this number?

kasra · August 18, 2022, 4:28pm

could you clarify this please ? what do you mean by using this number ?
yes I called this function in another file , I mean this func : number_of_NFT = advanced_collectible.TokenId()

cryptokid · August 18, 2022, 4:39pm

Where you get the error, what parameters are you using?

kasra · August 19, 2022, 6:02am

sorry I lost my conncetion .
when I run the command below I get the Error.
it can not recognize the TokenId it returns : URI query for nonexistent token

if not advanced_collectible.tokenURI(TokenId).startswith("https://"):

          print("Setting tokenURI of {}".format(TokenId))

Add some logging for that token id that is used as parameter. To see what is the value. Then see if it is the expected value or not.

kasra · August 19, 2022, 6:55am

OKay I’m not really experienced in using Logging , so could you please tell me how to define the logging for the specific value in the command below ? :

def main():

    print("Working on " + network.show_active())

    advanced_collectible = getMultiDataTypeTemplate[len(getMultiDataTypeTemplate) - 1]

    number_of_NFT = advanced_collectible.TokenId()

    #print(advanced_collectible.address)

   # print(advanced_collectible.tokenURI(TokenId))

    print(

        "The number of tokens you've deployed is: "

        + str(number_of_NFT)

         

    )

    for TokenId in range(number_of_NFT):

        breed = get_breed(advanced_collectible.TokenId())

        print(breed)

        print(TokenId)

        print(number_of_NFT)

        print(advanced_collectible.tokenURI(TokenId))

        if not advanced_collectible.tokenURI(TokenId).startswith("https://"):

          print("Setting tokenURI of {}".format(TokenId))

      set_tokenURI(TokenId, advanced_collectible,

             #            Status[breed])

The error specifically comes after this line :

print(advanced_collectible.tokenURI(TokenId))

        if not advanced_collectible.tokenURI(TokenId).startswith("https://"):

          print("Setting tokenURI of {}".format(TokenId))

Just use a print to print the value. That is what I wanted to say
