Connecting and Reconciling with a Wikibase instance

Hi, I'm a user with a local instance of wikibase.

I have installed the wikibase instance using the docker image pipeline distributed by Wikimedia Germany and I am currently working on enabling the upload of my datas via openrefine.

For that, I created an entpoint using the interface OpenRefine Wikibase NFDI4Culture / TA1 data enrichment / OpenRefine Wikibase · GitLab
and generated a manifest, but the problem is that when I connect with my local wikibase instance, I get follwing error:

Guess Types query failed error : java.io.IOException: HTTP error 403 : for URL /en/api

The manifest used is as follows:

{
    "version": "2.0",
    "mediawiki": {
      "name": "Ordi",
      "root": "https://localhost:3030/wiki/",

      "api": "https://localhost:3030/w/api.php"
    },
    "wikibase": {
      "site_iri": "https://localhost:3030/entity/",
      "maxlag": 5,

      }
    },

    },

         "reconciliation_endpoint": "http://localhost:8000/${lang}/api",
         "mediawiki_api": "https://localhost:3030/w/api.php"
      },
      "property": {
         "site_iri": "https://localhost:3030/entity/",
         "mediawiki_api": "https://localhost:3030/w/api.php"
      },
      "mediainfo": {
         "site_iri": "https://localhost:3030/entity/",
         "reconciliation_endpoint": "http://localhost:8000/${lang}/api"
      }
    },
    "editgroups": {
      "url_schema": "([[:toollabs:editgroups-commons/b/OR/${batch_id}|details]])"
    }
  }

Any help would be appreciated.
