V2, V3 price quotes#171

For some tokens I get an error when quoting the price in Uniswap V3, meanwhile in V2 everything is OK.
Error code is:
raise ContractLogicError('execution reverted')
web3.exceptions.ContractLogicError: execution reverted

Please help me to understand the reason.

Check if there is proper pool @ V3. Check what fee has been set for it. Default value for V3 fee is 0.3% or fee=3000 for get_price/make_trade calls. Other values are 0.05% (fee=500) and 1% (fee=10000)
