Error from the getAllNFTs from solidity

[llPekoll]

Hi first thanks for all your videos. I am working with solidity Part 5 files When create few NFT and I call getAllNFTs() function from the front It works few times then, without changes it stop working properly I get error message as return

I am on Bianance Smart Chain test net btw this is the return from the call

you can see the result here: https://nftl-trades.com/

data = {code: 3
data: "0x4e487b710000000000000000000000000000000000000000000000000000000000000032"
message: "execution reverted"}

All other function works properly tho
