fluffy can't decode find_content returned enr empty

[KolbyML]

fluffy can't decode find_content returned enr empty. I found this well working on tests for portal-hive

The error Error: Unable to get response from FINDCONTENT request: Call(Custom(ErrorObject { code: ServerError(-32000), message: "portal_historyFindContent raised an exception", data: Some(RawValue("No content response")) }))

trin -> fluffy passes because fluffy is sending an empty enr [] correctly, hence it is a issue with decoding

@kdeme not sure if I should ping or leave this here so I will ping since fluffy is your thing

Indeed, seems the fluffy node hits a decoding error:

DBG 2023-07-28 09:22:49.135+00:00 Error receiving message response           topics="portal_wire" error="Invalid message encoding" srcId=af*642b60 srcAddress=some(172.17.0.5:9009) protocolId=500b

I will investigate.

With slightly improved error message:

DBG 2023-07-28 13:22:29.874+00:00 Error receiving message response           topics="portal_wire" error="Invalid message encoding: SSZ None: invalid empty for selector" srcId=35*8b5718 srcAddress=some(172.17.0.5:9009) protocolId=500b

Fixed in #1909
