Ink! ink_env::debug_println! does not work if message is payable

Question

Adding #[ink(payable)] to a #[ink(message)] prevents ink_env::debug_println! messages to be logged in console when executing the smart contract call.

Any additional config needed in this case to have ink_env::debug_println! in console?

Answer 1

Debug messages are only emitted during a dry run (query), not during the actual transaction (tx)(Source).

When you're calling the contract, first query it. Then perform your transaction if there are no error messages.

e.g.

public async transaction(signer: Signer, method: string, args: any[]): Promise<Partial<TransactionResponse>> {

    // View any debug in substrate logs and catch any errors here
    const queryBeforeTx = await await this.contract.query[method](this.account.address, {}, ...args);

    // Then run your transaction
    const extrinsic = this.contract.tx[method]({}, ...args);
