Hi! We do support properly inferred parameter values when the => syntax is used. You can set get a null parameter like so :param foo => null. We're aware it's confusing that the different syntaxes work differently under the hood and have fixed it in Neo4j Workspace, but it's not made its way back to Neo4j Browser yet
