# Troubleshooting Errors 💡

Common error messages and how to solve them

**TRANSFER\_FROM\_FAILED** --> GASLIMIT too low. Raise it to GASLIMIT = 1000000 at least

**TRANSFER\_FROM\_FAILED** --> Your BASE token is not approved for trade

**INSUFFICIENT\_OUTPUT\_AMOUNT** --> SLIPPAGE too low

**TRANSFER\_FAILED** --> Trading is not enabled. Use WAIT\_FOR\_OPEN\_TRADE parameter after reading wiki

**TRANSFER\_FAILED** --> There is a whitelist

"**Sorry, We are unable to locate this TxnHash**" --> You don't have enough funds on your wallet to cover fees

... or your node is not working well

You're trying to swap tokens, but your **slippage tolerance is too low** or liquidity is too low.

SolutionReason

1. Try **trading a smaller amount** at one time.
2. **Increase your slippage** tolerance
   1. "SLIPPAGE": "49",
   2. If it does not work, go to settings.json and put : "UNLIMITEDSLIPPAGE": "true"
3. Lastly, try inputting an amount with **fewer decimal places**.

This can happen when you **don't put enough Gas Limit.**

Check if you don't have this in your transaction page :

This can happend when you're trying to buy a token where **buying is limited to whitelisted wallets only** in the beginning of the sale

Solution

There's nothing to do... you cannot buy if you're not on the whitelist 🤷‍♂️
