InvalidFrameProtocolException: Invalid version of beats protocol: 10

I'm trying to send data from filebeat version 5.6.4 (amd64), libbeat 5.6.4 to Logstash 7.4.2. I've tested the configuration sending filebeat version 7.4.2 from another server and I can see the data flowing OK from filebeat -> logstash -> elasticsearch.

However when I run the configuration for the filebeat 5.6.4 it fails with an exception in Logstash and I can see in the debug logs this below:

Is there any way I can troubleshoot this any more?
