Not able to mint NFT of any lesson

[tamoghna-dey]

I have completed till lesson number 6 but I am not able to mint any NFT even after solving the challenge. Everytime I press write button on sepolia etherscan it shows like the picture attached, in metamask and the transaction fails.

This is a general error in solidity when there is something wrong in the contract.

In the challenges this error is given when the answer is wrong.

Have that been the case then, I would have been able to mint the first lesson NFT, where we just need to put the Twitter handle and write the contract.

@tamoghna-dey This means you did not solve the challenge yet.

@tamoghna-dey Is it a lesson 2 challenge? And are you using this address for the first time to mint this nft?

[tamoghna-dey]

This is a lesson 2 challenge - 0x5c1ddb86F11BB46D3067C702AC554aEaED9ff8f0
I am minting it on sepolia, I have tried multiple times to mint it, with the same address but the problem remains same

@tamoghna-dey Working fine for me!

[tamoghna-dey]

Yaa, I made a new account on Metamask and then tried to mint, then it worked. Still don't know what the exact issue is.
@alymurtazamemon , @ChefAharoni thanks for your response guys!
