I’m experiencing a failure while trying to deploy my NFT contract on the development network with Anchor. The error message I receive is:
Error: Deployment failed: Error processing Instruction 1: custom program error: 0x1
Failed with: Output { status: ExitStatus(unix_wait_status(256)), stdout: "", stderr: "" }.
I’ve set my configuration to the devnet and ensured my wallet has sufficient SOL tokens from the faucet for deployment. The process initiates but fails, showing this confusing error code. Has anyone faced this particular custom program error before? I’m unsure about the meaning of instruction 1 or the reasons behind this 0x1 error during deployment. Any advice on how to troubleshoot or common issues that lead to this kind of deployment failure would be greatly appreciated.
sounds like your contract might be missing some initial data. double-check if the metadata for your nft is set up right before you try to mint. that 0x1 error often signals an account issue in anchor.
This 0x1 error usually means there’s a problem with account space allocation when deploying your contract. I ran into this same issue - turned out I hadn’t reserved enough space for the contract bytecode in the program account. Check your Anchor.toml file first to make sure the program ID matches what you’re actually deploying. Also verify your program account has enough space initialized. You can fix this by running solana program deploy with the --buffer flag or tweaking the space allocation in your deployment config. Another common cause is trying to deploy over an existing program without the right upgrade authority. Try deploying to a fresh program ID or double-check that you’ve got the proper upgrade authority set for the existing program account.
That’s a tricky one! I’ve hit similar custom program errors before - they’re pretty cryptic. The 0x1 error code means something went wrong during instruction processing, but Anchor doesn’t always tell you what exactly failed.
Try checking your program logs more closely. Run solana logs in another terminal while deploying - you’ll get more detailed info about what’s happening when instruction 1 fails.
Also check your anchor.toml setup. Does the program ID match what’s in your lib.rs file? I’ve seen mismatches cause weird deployment issues that show up as generic program errors.
What Anchor version are you using? Try deploying a simple “hello world” program first to see if it’s your NFT contract specifically or a general setup issue.
One more thing - when you say you have sufficient SOL, how much exactly? NFT contracts can be pretty large and sometimes need more SOL than expected for deployment. Just ruling out the obvious stuff first!
