rpc.txfeecap is not being respected

[eldarbogdanov]

Attempting to send transaction through eth_sendRawTransaction with tx fee above 1 ether fails with txFee ... exceeds the configuration cap error, in spite of Erigon client running with unlimited cap (--rpc.txfeecap 0). The code looks like it's using the default RPCTxFeeCap instead of the user-provided one.

System information

Erigon version: any

Erigon Command (with flags/config): erigon --rpc.txfeecap 0 ... yadayadayada ...

Chain/Network: Amoy

Expected behaviour

eth_sendRawTransaction should allow providing fees above the user-configured rpc.txfeecap limit.

Actual behaviour

eth_sendRawTransaction caps fees at the default (1 ether) and fails with txFee ... exceeds the configuration cap (1.00 ether).

Steps to reproduce the behaviour

Run the client with non-default rpc.txfeecap and run eth_sendRawTransaction with fee above this default.
