GS013 error when executing Gnosis Safe transaction

Question

I have created the following transaction in the Gnosis Safe Service: https://gnosis-safe.io/app/rin:0x62c1bC4236F7df56D7475a1B95463236e3d85947/transactions/queue

This was created using the SDK:

const safeTransaction = await safe.createTransaction({
        to: toAddress,
        value: ethers.utils.parseEther(String(amount)).toString(),
        data: `0x${uuid.replace(/-/g, "")}`,
});

const safeTxHash = await safe.getTransactionHash(safeTransaction);
await safeService.proposeTransaction({
          safeAddress,
          safeTransaction,
          safeTxHash,
          senderAddress,
});

2/2 signers have confirmed the transaction in Gnosis Safe. When trying to execute the transaction I get the following error message: This transaction will most likely fail. To save gas costs, avoid creating the transaction.

And when proceeding anyway, incl manually setting the gas limit, I get the GS013 error: Safe transaction failed when gasPrice and safeTxGas were 0 Transaction: https://rinkeby.etherscan.io/tx/0x2f0e6b7b0dbbc14d01c2927397fbf066ab0aaede6fcdee6acd333c6b82a1ee3d

Where do I make sure that gasPrice and safeTxGas aren't 0?

Answer 1

The problem here is not the safeTxGas and gasPrice. If you would set these value, the internal Safe transaction would still fail.

Looking at your transaction I can see that you try to transfer 8000000000000000 WEI which amounts to 0.008 ETH but the Safe only has 0.002999 ETH, therefore the transaction fails because of insufficient funds.
