Getting an error `InstructionPackError: Failed to pack instruction data` when trying to create a new NFT

[nikhilasrani]

Hey folks, I'm getting an error when trying to run const { nft } = await metaplex.nfts().create({ uri }); The upload metadata step works fine and produces a uri with metadata that is identical to the ones that were working with the create NFT step before.

But when I run the above code, I get the following error

ParsedProgramError [MetaplexError]: TokenMetadataProgram > Failed to pack instruction data

The package versions I am using are "@solana/web3.js": "^1.41.3", "@metaplex-foundation/js": "^0.11.5"

Hi there 👋 Thanks for raising this. I'll look into this asap. 🙂

[lorisleiva]

I'm afraid I can reproduce this issue. Would you be able to provide a public repository with the minimum amount of code to reproduce this issue?

[nikhilasrani]

hey @lorisleiva, I figured out the problem. It's rather quite silly, I think the this error starting showing up when we had an empty wallet/ no Solana balance to fund the creation of the NFT.

Once I added some SOL to my wallet, it began working as expected. Thank you for your prompt response and support. I really appreciate it.

Closing this issue with this comment so that maybe it can help others who face the same issue.

@nikhilasrani Thanks for putting in your solution - it certainly helped me! I think the issue should remain open though as Failed to pack instruction data doesn't really help metaplex developers know the cause of the issue is an insufficient balance. Likewise other Solana apps - SPL, web3, etc. - simply say insufficient balance in this scenario.

Version is @metaplex-foundation/js@0.15.0 - will try and see if this occurs on a newer version but have some issues running 0.17 so far due to some http polyfilling.
