1. 1 .
  
  Tap the settings icon on the liquidity folio.
2. two .
  
  Increase your slippage tolerance a picayune and try again.

This commonly happens when trading tokens with depression liquidity.

That ways there isn't enough of one of the tokens you lot're trying to swap in the Liquidity Pool: it's probably a small-cap token that few people are trading.

Nevertheless, there's likewise the chance that y'all're trying to trade a scam token which cannot be sold. In this example, PancakeSwap isn't able to block a token or return funds.

INSUFFICIENT_A_AMOUNT or INSUFFICIENT_B_AMOUNT

Fail with error 'PancakeRouter: INSUFFICIENT_A_AMOUNT' or Neglect with error 'PancakeRouter: INSUFFICIENT_B_AMOUNT'

You're trying to add/remove liquidity from a liquidity pool (LP), but at that place isn't plenty of ane of the two tokens in the pair.

Refresh your page and try again, or try again after.

1 .

Tap the settings icon on the liquidity page.

Information technology might exist the case that prices are updating too fast when and your slippage tolerance is too low.

OK, then you're actually determined to fix this. We really don't recommend doing this unless yous know what yous're doing.

In that location currently isn't a simple way to solve this event from the PancakeSwap website: you'll demand to collaborate with the contract directly. You can add liquidity directly via the Router contract, while setting amountAMin to a small amount, and so withdrawing all liquidity.

v .

Set a low amountAMin or amountBMin : try 1 for both.
vi .

Add together your wallet accost in to (address) .
7 .

Deadline must be an epoch time greater than the time the tx is executed.

PancakeRouter: EXPIRED

The transaction cannot succeed due to error: PancakeRouter: EXPIRED. This is probably an upshot with i of the tokens you are swapping.

Try once more, merely confirm (sign and broadcast) the transaction as soon as you generate information technology.

This happened because you started making a transaction, merely you didn't sign and broadcast it until it was past the deadline. That means you didn't hit "Confirm" apace enough.

If you desire to sell the maximum possible, endeavour seventy% or 69% instead of 100%. Acquired past the pattern of Restorative Rebase tokens similar tDoge or tBTC. Understand how restorative rebase tokens work .

Another possible cause of this effect is the malicious token issuer merely suspended the trading for their token. Or they made selling activeness only possible for selected wallet addresses. Please always do your own research to avert any potential fraud. If the token you are trying to swap but failed with this error code is coming from an airdrop, that is most probable a scam. Please practise not perform any token approval or follow whatsoever links, your fund may be at risk if you effort to do and then.

If you got this error while removing liquidity from a BNB pair:

Please select "Receive WBNB" and retry.

If you got this mistake while trying to bandy:

Please contact the project team of the token you're trying to swap. **** This event must be resolved past the projection team.

This outcome (while swapping) is caused by tokens which have difficult-coded the V1 PancakeSwap router into their contract.

While this practice is ill-advised at best, the reason for these projects having washed this appears to be due to their tokenomics, in which each purchase sends a % of the token to LPs.

The projects affected will likely not piece of work with the V2 router: they will most probable need to create new versions of their tokens pointing to our new router address, and migrate any existing token holders to their new token.

We recommend that any projects which created such tokens should also make efforts to prevent their users from adding them to V2 LP.

Cannot read property 'toHexString' of undefined

"Unknown error: "Cannot read property 'toHexString' of undefined"

Bug with Syrup Pools

BEP20: burn amount exceeds balance

Neglect with error 'BEP20: burn amount exceeds balance'

You lot don't accept plenty SYRUP in your wallet to unstake from the Cake-Block pool.

Get at least as much SYRUP every bit the amount of Block that y'all're trying to unstake.

1 .

Purchase SYRUP on the exchange. If y'all want to unstake 100 CAKE, you need at least 100 SYRUP.

If that notwithstanding fails, you can perform an "emergencyWithdraw" from the contract directly to unstake your staked tokens.

2 .

Click "Connect to Web3" and connect your wallet.
3 .

In section "4. emergencyWithdraw" , enter "0" and click "Write".

This volition unstake your staked tokens and lose whatsoever uncollected CAKE yield.

This volition lose any yield that you haven't harvested yet.

To cease this happening again, don't sell your SYRUP. Yous still demand information technology to unstake from the "Stake CAKE Earn Cake" pool.

This error has happened because you lot have sold or transferred SYRUP tokens. SYRUP is minted in a 1:i ratio to CAKE when you pale in the Block-Block Syrup Pool. SYRUP must be burned at a 1:1 ratio to CAKE when calling leaveStaking (unstaking your Block from the puddle), so if y'all don't take enough, you lot can't unstake from the puddle.

Out of Gas mistake

Warning! Error encountered during contract execution [out of gas]

You have set a low gas limit when trying to make a transaction.

Try manually increasing the gas limit (not gas price!) in your wallet before signing the transaction.

A limit of 200000 is usually enough.

The higher up example is from Metamask; check your wallet'south documentation if yous aren't sure how to conform the gas limit.

Basically, your wallet (Metamask, Trust Wallet, etc.) can't end what it'due south trying to do.

Your wallet estimates that the gas limit is also low, so the function telephone call runs out of gas before the part phone call is finished.

BEP20: transfer amount exceeds assart

Fail with error 'BEP20: transfer amount exceeds assart'

1 .

Use Unrekt.net to revoke approving for the smart contract you're trying to interact with
2 .

Approve the contract over again, without setting a limit on spend allowance
iii .

Endeavour interacting with the contract again.

This happens when you fix a limit on your spend allowance when you first approved the contract, then try to swap more than than the limit.

BEP20: transfer amount exceeds balance

Fail with mistake 'BEP20: transfer corporeality exceeds balance'

Y'all're probably trying to unstake from a Syrup Pool with low rewards in it. Solution below.

If not, you may be trying to send tokens that y'all don't have in your wallet (for example, trying to ship a token that is already assigned to a awaiting transaction). In this case, but make certain you have the tokens y'all're trying to utilize.

Firstly, let the team know which puddle you're trying to unstake from, then they tin top up the rewards. If y'all're in a hurry to unstake and you don't heed losing your awaiting yield, try an emergencyWithdraw:

You can perform an "emergencyWithdraw" from the contract directly to unstake your staked tokens.

1 .

Observe the contract address of the Syrup Puddle you lot're trying to unstake from. You lot can discover it in your wallet'due south transaction log.
4 .

Click "Connect to Web3" and connect your wallet.
5 .

In section "iii. emergencyWithdraw", and click "Write".

This will unstake your staked tokens and lose any uncollected yield.

This will lose any yield that you haven't harvested yet.

This mistake tends to appear when yous're trying to unstake from an old Syrup Pool, just there aren't enough rewards in the pool left for you to harvest when withdrawing. This causes the transaction to fail.
