Solana: Getting block height errors when requesting NFT minting using metaplex [duplicate]

Title: Solana: Errors Exceeding Block Height When Creating NFTs with Metaplex

Introduction

Mining a non-fungible token (NFT) on the Solana blockchain can be an exciting experience. However, I have encountered an error that is causing problems when trying to create an NFT on the platform: “Block height exceeded.” This article provides troubleshooting steps and solutions to resolve this issue.

Problem

When trying to create NFTs using Metaplex, I have noticed that I am getting the infamous “Block height exceeded” error. This happens if my transaction exceeds Solana’s maximum allowed block height. As a result, the blockchain rejects the transaction and I have to start over.

Solution

Luckily, there are some solutions to this problem:

1. Add a Tx Priority Fee

One way to solve this problem is to add a priority fee to the transaction using the “–priority-fee” option when sending the NFT fake transaction. Here is an example of how to do this:

solana mint --tx-priority-fee=1000 mymetaplex-nft.json

This will set the transaction priority fee to 1000 SPK (Solana Plasma Kintsugi). The “–priority-fee” option is a new feature in Solana 1.10, and it allows you to set a custom fee for each transaction.

2. Use a different transaction structure

You can also try using a different transaction structure that is not based on the “–priority-fee” option. One way is to use the command “solana mint –tx-type=script” with a script that includes a function that adds the priority fee:

solana mint --tx-type=script mymetaplex-nft.json \
"function addPriorityFee(amount: u128) {
if (amount > 0) {
constantfee = await solana.client.fee(1000);
returnamount + fee;
} else {
returnamount;
}
}"

This script adds the priority fee to the transaction amount before minting the NFT.

3. Check Solana documentation and forums

Before trying these solutions, I recommend checking the official Solana documentation and forums for updates or new information.

Conclusion

Sometimes mining NFTs on the Solana blockchain can be a bit tricky, but with the right approach, you should be able to resolve the “Block height exceeded” error. By adding priority fees to your transactions or using alternative transaction structures, you can overcome this issue and successfully create NFTs.

Recommendations

• Be sure to check the latest Solana documentation for any changes or updates.

• If you are having issues with Metaplex, try upgrading to the latest platform version (1.10.x or later).

• Consider using a different transaction structure that is not based on priority fees.

I hope this article helped you resolve the “Block height exceeded” error when creating NFTs on Solana!
