HOW TO FIX SWAP FAILED : REPLACEMENT FEE TOO LOW ERROR ON PANCAKESWAP & METAMASK

Usually when you try to buy a token with a very low gas fee, the contract might also have altered the settings on your Metamask which often gives the following error code:

Swap failed: replacement fee too low (error={“code”:-32603,”message”:”Error: [ethjs-query] while formatting outputs from RPC ‘{“value”:{“code”:-32603,”data”:{“code”:-32000,”message”:”replacement transaction underpriced”}}}'”,”stack”:”Error: Error: [ethjs-query] while formatting outputs from RPC ‘{“value”:{“code”:-32603,”data”:{“code”:-32000,”message”:”replacement transaction underpriced”}}}'”}, method=”sendTransaction”, transaction=undefined, code=REPLACEMENT_UNDERPRICED, version=providers/5.0.19)
