"Transaction simulation failed: Attempt to load a program that does not exist"

Question

Trying to create an NFT collection using metaplex and have been getting stuck with this error while trying to interact with the program using a nextjs client.

Here is the repo https://github.com/rtwhite10/token_2022_nft

I have seen that this error is usually related to testnet not having metaplex programs available but im testing using devnet so im a little confused.

Wondering if it has something to do with the program call here?

I have two programs that are very similar mint-nft which uses token-2022 and also mint-nft-standard which does not. Both are returning the same error. I created the standard as I was thinking it could be related to my token 2022 implementation in both theses programs mint_nft.rs & create_collection.rs

Thanks!

I figured it out, this was because my program was not deployed correctly. I somehow deployed it previously but the address was not the same as the one found in the IDL for the program. Re-deployed and now the error is gone. But I have a new error... hahaha
