BoltSips crashing with error Unsupported encoder version

I get this error when I try connecting to neo4j using BoltSip

(Bolt.Sips.Internals.PackStreamError) Unsupported encoder version [bolt_version: 0, data_type: struct, data: {1, [“BoltSips/2.0.11”, %{}]}]

The command to connect to neo4j is Bolt.Sips.start_link([url: "bolt://localhost:7687"])
Neo4j version is 5.1.0

Can I get some help resolving this issue?
Thanks
