Hi Neha,
I found your project on youtube and was not able to see where and how the metadata.json file was read by your application.
Is the api of pinata accept either an image file or a json file ? Could make sense
Thanks
Hi Neha,
I get a similar error to the one mentioned earlier -
Error occured while storing data to file Error: Configuration property "ipfsFile.location" is not defined
at Config.get (D:\GitHub\yoriverse\node_modules\config\lib\config.js:182:11)
at storeDataToFile (D:\GitHub\yoriverse\scripts\ipfsHelper.js:10:50)
at pinFileToIPFS (D:\GitHub\yoriverse\scripts\pinFileToIPFS.js:29:11)
at processTicksAndRejections (internal/process/task_queues.js:95:5)
Successfully added IPFS response to json file
Prior to this error I also get the output
data: {
IpfsHash: 'QmbAVkKcEiLSjXUYpYuTKipJYZmoVgeV85PahG6Fp1D5Sc',
PinSize: 224676,
Timestamp: '2022-05-22T12:00:50.187Z',
isDuplicate: true
}
But no data folder is being created.
I tried setting the NODE_ENV to dev. Anything else I am missing?
Hello Neha,
The following command does not work on the mainnet :
npx truffle migrate --network matic
Here is my .env file :
PINATA_API_KEY="*"
PINATA_API_SECRET="*"
PINATA_ENDPOINT="https://api.pinata.cloud/pinning/pinFileToIPFS"
MNEMONIC="*"
CLIENT_URL="https://polygon-rpc.com/"
CONTRACT_ADDRESS="YOUR_DEPLOYED_CONTRACT_ADDRESS"
The transaction are visible on polygonscan but I get an error when I reach 750 seconds with the following error :
Error: *** Deployment Failed ***
"Migrations" -- Transaction was not mined within 750 seconds, please make sure your transaction was properly sent. Be aware that it might still be mined!.
