Hi!
The successful swap was done using a V3 pool (command: 0x00), while the failed one was done using a V2 pool (0x08) which does not exist.
Very happy you find it wonderful!! :) You will find an address in the wiki page footer: https://github.com/Elnaril/uniswap-universal-router-decoder/wiki |

Did you use the same account ? In this case, you should probably not use the same Permit2 nonce (0) again. |

no. I take nonce via code. Wrapped everything

TBH, I don't see anything wrong in your last transaction, and it looks very much like successful ones ... |

Hi There!
It seams they have changed something in contract logic.
The transaction that passes has data like this:
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
