Subject: Solr 6.6.3: Errors when using facet.field

Hi,
I am running a simple query with group by & faceting.

facet=true&group=true&group.facet=true&group.field=product_id&group.ngroups=
true&facet=true&facet.field=product_id&facet.mincount=1


When I run the query I get errors

The above query worked in solr 5.3. Any suggestions ?
Thanks
