GUI is breaking when reading a specific json record

Couchbase GUI is breaking when reading a specific json record in the "Documents" page.

In detail: When a document exists in the DB with these (or similar) data (image):
{{}}

{

  "test": [

    {

      "test1::test2": {

        "test3": "test4"

      }

    }

  ]

}

then, the whole GUI is failing, no data are shown, and navigation starts being problematic. 

As you understand, there is no way to use the GUI to see or edit any document if this error occurs.

Best,
