Solana deploy "account data too small for instruction"

Question

When i try to deploy a program with anchor (devnet or mainnet, same error), i get the following error : Deploying program failed: Error processing Instruction 0: account data too small for instruction.

I have no clue where this comes from.

The so file is around 331Ko, and apparently, the error shows up when i try to use "mpl-token-metadata" to get metadata of NFT

Any one has an idea how to correct that ?

Answer 1

You don't have to redeploy your program.

Using Solana CLI (>1.18) you can do:

$ solana program extend <PROGRAM_ID> <MORE_BYTES>

To allocate more bytes, then try again.

Answer 2

Delete the target folder

Run anchor build, this will add a new keypair to target/deploy

run anchor keys list, this will give you the new program id

copy the id to the top of your lib.rs

run anchor build again

and anchor deploy
