Solana counter example success on localnet but failed on devnet: Attempt to debit an account but found no record of a prior credit

Question

I'm working on Counter example of Solana. Everything works well on localnetwork, but when I try on devnet I got the message

Transaction simulation failed: Attempt to debit an account but found no record of a prior credit.

I send SOL to counter's public key, but it doesn't help.

What could I do and why localnet is ok but devnet failed?

Answer 1

You do need to have devnet sol in your signer account to perform transactions on devnet. You can see that current signer like this:

solana address

then you can do

solana airdrop YourAddress -ud

Where -ud stands for devnet -um for mainnet and -ul for localnet

If that does not work your can also use faucet.solana.com

Then you can run your script again.
