Inability to call certain functions

Smart Contracts

I deployed an ERC721A contract that imports OZ's libraries and verified it's source code successfully on HardHat. But the problem is, I can't call the mint function, nor the pause function on Remix. I get this error:

Gas estimation failed
Gas estimation errored with the following message (see below). The transaction execution will likely fail. Do you want to force sending?
Cannot read properties of undefined (reading 'includes')

All other functions work well, except these two. I tried to change my evm version to paris, but it didn't even work.

Hi, welcome to the community. :wave:

It seems like you do not pass a valid eth value when call the function mint(), and now, it seems like you have found this, and called it successfully. Congrats!

If there are no other more questions, I would like to close this topic.

What do you mean when you say that I don't pass a valid eth value?

Here:

Should call mint() with eth to meet the requirement:
require(msg.value >= quantity * mintPrice, "Insufficient Funds");

Ah! I had minted directly from Etherscan.
Thank you so much for the help, you can close this.
