custom program error: 0x0

[easydeveloppement]

Hello,
when i run anchor test, it fails initializing escrow account with error "custom program error: 0x0".
afaik, it means one account lack sols. But i don't know which one...
I have enough SOL in the payer account for sure.
I even have SOL in escrow account...
WHat could it be ? Anyone has an idea ?

here are the logs

Hi, it means the account with that address is already created.

Which cluster are you connecting to?

Hi, i'm using devnet.
So it means an escrow account can only be used once i guess.
So if i want to test this script, the escrow account must be different every time ? So i just need to change the seed phrase for this account ? (in rust & in JS)

what i don't really understand is which account is already created ?
Because it seems to be the escrow account (so my last comment makes no sens about the seed phrase, because it's for PDA)
=> but the escrow account is created for every test with const escrowAccount = anchor.web3.Keypair.generate();

so how could it be already created ? Furthermore, when i check on solana explorer, it displays no activity before my test.

So i think there might be something that i don't get ?

Ok, i think i understood.
I modified the JS testing script, and i was airdroping some SOL to the escrow account (i think i had an error that i didn't get, and tried that...), as soon as i removed it, it worked perfectly.
And for information, i could run more than once with the same "escrow" and "token-seed", si no need to update them.

Thank you so much for your help !!!
