dynamic_mapping.template_meta_types.mapping.path is invalid in ElasticSearch 8

We have recently update to ElasticSearch 8 and since we can see following errors:

dynamic template [template_meta_types] has invalid content, attempted to validate it with the following match_mapping_type: [object, string, long, double, boolean, date, binary], last error: [Unknown mapping attributes [{path=full}].

The relevant portion of the mapping is:

        {
          "template_meta_types" : {
            "path_match" : "meta.*",
            "mapping" : {
              "path" : "full",
              "properties" : {
                "date" : {
                  "format" : "yyyy-MM-dd",
                  "type" : "date"
                },
              },
              {…},
              "type" : "object"
            }
          }
        }

As I took over managing the ES server, I am not entirely sure the reason for this as this field seems to be either deprecated or removed.

What is the correct solution for this? Should I completely remove this field? What would be the correct way?
