# Error Messages

## insufficient funds

{% hint style="danger" %}
Fail to buy PRIV token for 0.125 ETH \~$291.49 by API buy command. Attempt 3. Fail to send transaction, type=\<class 'ValueError'>, message=ValueError({'code': -32000, 'message': '<mark style="background-color:red;">insufficient funds for gas</mark> \* price + value: balance 141947753571836880, tx cost 149184184735500000, overshot 7236431163663120'})
{% endhint %}

The error message indicates that your wallet does not have enough funds to cover the transaction cost, which includes both the amount to buy the token (0.125 ETH) and the gas fees.

Solution: Verify that your wallet has sufficient funds not only to buy the token but also to cover gas fees. Add more ETH to your wallet to cover both the purchase cost and gas fees.

## Smart Contract Issues

{% hint style="danger" %}
Fail to sell 100% of FUXI token for \~$41.91 by time fix.. Attempt 4. Fail to build transaction, type=\<class 'web3.exceptions.ContractLogicError'>, message=execution reverted: TransferHelper: <mark style="background-color:red;">TRANSFER\_FROM\_FAILED</mark>
{% endhint %}

Smart Contract Issues: The FUXI token’s smart contract or the DEX may have restrictions or bugs preventing the transfer.

Check Contract: Review the FUXI and DEX smart contract documentation to ensure there are no additional requirements or restrictions.

## Insufficient Liquidity or low slippage

{% hint style="danger" %}
Fail to sell 100% of Au token for \~$92.41 by time fix.. Attempt 4. Fail to build transaction, type=\<class 'web3.exceptions.ContractLogicError'>, message=execution reverted: <mark style="background-color:red;">UniswapV2: INSUFFICIENT\_OUTPUT\_AMOUNT</mark>
{% endhint %}

### Insufficient Liquidity

The liquidity pool might not have enough token volume to execute the trade.

Check Liquidity: Ensure that the liquidity pool for Au and ETH (or another pair) has sufficient volume.

### Low slippage

The message from UniswapV2 indicates that the amount of received funds is less than the minimum expected. This could be due to high price volatility or slippage settings.

Increase Allowed Slippage: Adjust the bot’s settings to allow a higher slippage tolerance when executing the trade.
