Mint issue: Error processing Instruction 4

[AoDev]

Hello, thanks for this great project!

Setup

• The site is running locally using devnet.
• No changes to the repo code, only set NEXT_MINT_PRICE_SOL=0.01 in .env for testing purposes
• I created a wallet on devnet using phantom and connected to the site.

Issue

I'm trying to mint 1 and getting this error:

A has_one constraint was violated

Checking the wallet instructions:

You should be creating your candy machine as per the readme.md, as well as generating its unique env file and everything. It does not work like as simple as updating the env files.

I know. I ran the setup script and followed the instructions. Anyway, it seems to be a bug. I found that deleting the cache folder and rerunning the setup script solved the issue.

Hmm... This could be a long name for your NFTs too that is more than the allocated space in the candy machine contract.
