I'm having real issues selling a token BUNNY for BNB on BSC. Here's what I know IS working

1. checking the allowance shows I have approval to trade BUNNY on the PCSv2 router
2. increasing the allowance also works
3. Spending BNB to buy BUNNY works also (swapExactETHforTokens)
4. manually writing into the contract on BSC scan also works

what doesn't work is swapExactTokensForETH - it spends some gas but throws up: "TRANSFER FROM FAILED"... reason: 'transaction failed', code: 'CALL_EXCEPTION' here's the failed transaction from the node.js script https://bscscan.com/tx/0x55d45e5f1e937fcd55294fa3e4d8c4c24d9c578b7ba8361fb12b2a017d7e7a4b

now all of the research i've done says it's because i need to approve the spender - I've done that... how do I know? well the function I wrote says it's fine as does querying BUNNY directly the other odd thing is that this worked perfectly (with no additional approval) - see screenshot

BSCScan Write Contract that works

here's the success transaction from the BSCscan write part of the router contract https://bscscan.com/tx/0xc8d2b999c08cef6ecceecf4bc5d6242bcd43571164016a8372bbf0c02d1a6185

If anyone can work out why this error is being thrown that would be a massive help tyvm in advance Here's the code:
