I'm running a new horizon v1.2 with ingest=true. It is connected to the stellar core with CATCHUP_COMPELTE enabled. (the status of the core is catching up 5%)

My question is what is the command to run the horizon to ingest all of the historical data? I used horizon serve the same as the previous versions of the horizon but doesn't ingest the old data.

I used horizon db reingest 1 29599089 and I get this error time="2020-05-11T14:19:55.542Z" level=error msg="Error in ingestion state machine" current_state="reingestHistoryRange(fromLedger=1, toLedger=29599089, force=false)" error="error processing ledger sequence=1: Error creating ledger reader: ledger not found" next_state=stop pid=1 service=expingest
