Bug on the Exchange

INSUFFICIENT_OUTPUT_AMOUNT

The transaction cannot succeed due to mistake: PancakeRouter: INSUFFICIENT_OUTPUT_AMOUNT. This is probably an effect with ane of the tokens yous are swapping.

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

1. ane .

   Refresh your page and try over again later.

2. two .

   Try trading a smaller amount at in one case.

3. iii .

   Increase your slippage tolerance:

   1. 1 .

      Tap the settings icon on the liquidity page.

   2. 2 .

      Increase your slippage tolerance a little and effort again. ​

      

4. 4 .

   Lastly, try inputting an corporeality with fewer decimal places.

This normally happens when trading tokens with low liquidity.

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

Still, there'south also the chance that you're trying to trade a scam token which cannot be sold. In this case, PancakeSwap isn't able to block a token or return funds.

INSUFFICIENT_A_AMOUNT or INSUFFICIENT_B_AMOUNT

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

You're trying to add/remove liquidity from a liquidity pool (LP), but there isn't enough of one of the two tokens in the pair.

Refresh your page and attempt again, or try once more later.

1. 1 .

   Tap the settings icon on the liquidity page.

2. ii .

   Increase your slippage tolerance a little and try again.

The error is caused by trying to add or remove liquidity for a liquidity puddle (LP) with an insufficient amount of token A or token B (one of the tokens in the pair).

It might be the case that prices are updating too fast when and your slippage tolerance is too low.

PancakeRouter: EXPIRED

The transaction cannot succeed due to error: PancakeRouter: EXPIRED. This is probably an outcome with one of the tokens y'all are swapping.

Try again, but ostend (sign and broadcast) the transaction every bit soon as you generate it.

This happened considering yous started making a transaction, simply you didn't sign and broadcast it until it was by the borderline. That means you lot didn't hit "Confirm" quickly enough.

Pancake: K

The transaction cannot succeed due to error: Pancake: K. This is probably an result with one of the tokens y'all are swapping.

Refresh the page and effort over again, or increase slippage tolerance via the settings icon and endeavour again.

This probably happened because you're trying to buy or sell tokens during a big toll movement. The frontend is getting outdated information (e.grand. outAmount) from the smart contract, causing the bandy to fail.

Problems with Paper Pools

BEP20: burn amount exceeds balance

Neglect with error 'BEP20: burn corporeality exceeds balance'

Yous don't take enough Paper in your wallet to unstake from the PTS-PTS Paper pool.

Become at least every bit much PAPER every bit the corporeality of PTS that you're trying to unstake.

1. 1 .

   Buy Newspaper on the exchange. If you desire to unstake 100 PTS, y'all need at least 100 PAPER.

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

2. 2 .

   Click "Connect to Web3" and connect your wallet.

   

   ​

3. 3 .

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

This will unstake your staked tokens and lose whatsoever uncollected PTS yield.

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

To end this happening again, don't sell your PAPER. Yous still need it to unstake from the "PTS-PTS" puddle.

This error has happened because you have sold or transferred Newspaper tokens. PAPER is minted in a 1:1 ratio to PTS when y'all stake in the PTS-PTS PAPER Pool. Paper must be burned at a 1:1 ratio to PTS when calling leaveStaking (unstaking your PTS from the puddle), and so if you don't accept enough, you lot can't unstake from the pool.

Out of Gas mistake

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

You accept set a low gas limit when trying to brand a transaction.

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

A limit of 200000 is normally enough.

The above instance is from Metamask; check your wallet'due south documentation if you aren't sure how to adjust the gas limit.

Basically, your wallet (Metamask, Trust Wallet, etc.) tin can't finish what information technology's trying to exercise.

Your wallet estimates that the gas limit is too low, so the function call runs out of gas before the function call is finished

BEP20: transfer amount exceeds balance

Fail with error 'BEP20: transfer corporeality exceeds residuum'

You're trying to unstake from a Syrup Pool with depression rewards in information technology.

Yous tin can perform an "emergencyWithdraw" from the contract direct to unstake your staked tokens.

1. 1 .

   Discover the contract address of the Syrup Pool you're trying to unstake from. You can find it in your wallet's transaction log.

4. four .

   Click "Connect to Web3" and connect your wallet.

   

   ​

5. five .

   In department "iv. emergencyWithdraw", enter "0" and click "Write".

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

This will lose whatever yield that you haven't harvested withal.

This mistake tends to appear when you're trying to unstake from an old Paper Pool, just at that place aren't enough rewards in the puddle left for y'all to harvest when withdrawing. This causes the transaction to fail.
