On optimism swap (no errors with same code on arbitrum), two errors pop up: ValueError: {'code': -32601, 'message': 'the method eth_maxPriorityFeePerGas does not exist/is not available'} and ValueError: {'code': -32601, 'message': 'the method eth_feeHistory does not exist/is not available'}

To Reproduce
uniswap V3 (0.03%tier), optimism, USDC to ETH token swap.

Expected behavior
Swap to occur

I tried all same code via alchemy api: get slightly different error, maybe it will help debug. Thanks

I have the same problem as you

[Alkhara]

Is there a way to force a legacy tx for networks like this @shanefontaine / @ErikBjare ?

[ErikBjare]

@Alkhara I'm not 100% certain, but it's possible you can work around this by providing a custom gas price strategy, since it's the automatic/default gas pricing strategy that fails (see the Web3py docs for how to do that).

Not sure you can force it to do a legacy tx that way, but otherwise you'll prob have to edit the source.
