Got error "account data too small for instruction" when run Anchor deploy?

Question

Sometimes I got this error when deploy program with running "anchor deploy":

Error: Deploying program failed: RPC response error -32002: Transaction simulation failed: Error processing Instruction 0: account data too small for instruction [3 log messages]
There was a problem deploying: Output { status: ExitStatus(unix_wait_status(256)), stdout: "", stderr: "" }.

So I have to run "anchor clean, cargo clean" and change cluster, sometimes it works, sometimes it doesnot, please help. how to fix this?

Answer 1

You'll need to extend your program size.

Hopefully you are using a version greater than .18

 solana program extend PROGRAM_ID 20000 -u d -k KEYPAIR_FILE_PATH

replace PROGRAM_ID and KEYPAIR_FILE_PATH with your own, e.g

 solana program extend HMDRWmYvL2A9xVKZG8iA1ozxi4gMKiHQz9mFkURKrG4 20000 -u d -k ~/.config/solana/id.json
