Research direction

Start at collector/node_conn.go line 75, where the subscription error is logged, then inspect the referenced go-ethereum gethclient subscription code and core/types/transaction_marshalling.go's txJSON handling. Determine why Infura's subscription result is no longer parsed and confirm that transactions can be received without the unmarshalling error.

Written by the indexing model from the issue text.

Description

Currently, subscriptions to Infura cause the following error:

json: cannot unmarshal string into Go value of type types.txJSON

The error is logged here: https://github.com/flashbots/mempool-dumpster/blob/7dd7061fc3f2a4128abe7fd0d1d88d56186be9e5/collector/node_conn.go#L75

It stems from the go-ethereum gethclient subscription code that's suddenly unable to parse the result from Infura subscriptions into txJSON.
