    After several investigations I found the issue but I didn't find the solution yet ...

    Using basic authentication, when I run the query I have following issue :

     

    "Expression.Error: The 'Authorization' header is only supported when connecting anonymously. These headers can be used with all authentication types: Accept, Accept-Charset, Accept-Encoding, Accept-Language, Cache-Control, Content-Type, If-Modified-Since, Prefer, Referer"
