Seems like one of the most commonly reported issue is about passing wrong params:

• web3.exceptions.ContractLogicError: execution reverted: Unexpected error uniswapv3 EUROC USDC pair #355
• execution reverted by new coin (even after liquidity added) #350

I suppose these happen if any of (version, fee, token0, token1) are wrong.

It might be helpful to catch these exceptions and re-raise them with more helpful error messages, as I wrote here: #355 (comment)

We might also want to remove the 0.3% assumption and just raise an exception if not set for V3: #355 (comment)
