Reindex catalogsearch_fulltext

Check my Magento 2 category pages, I get the error below

“We can’t find products matching the selection.”

So I ran the command below

php bin/magento indexer:reindex catalogsearch_fulltext

But I got the error below

Catalog Search index process unknown error:
{“error”:{“root_cause”:[{“type”:”illegal_argument_exception”,”reason”:”request [/magento2_product_1_v2/document/_mapping] contains unrecognized parameter: [include_type_name]”}],”type”:”illegal_argument_exception”,”reason”:”request [/magento2_product_1_v2/document/_mapping] contains unrecognized parameter: [include_type_name]”},”status”:400}

Any suggestions?

Thanks!
