Note: the Nubentos API v1.0.0 is no longer available. You can use this API as a replacement:

That is a great idea to create a map between endpoint and paths. Thanks for sharing!

How does Flutter handle withCredentials httponly cookie requests? My API does not implement OAuth. We just use standard httponly session cookies.

Hi, I'm getting an HTTP/1.1 500 Internal Server Error. The response body is:


{
"code": "ER_PARSE_ERROR",
"errno": 1064,
"sqlMessage": "You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '' ORDER BY lastUpdated DESC limit 1' at line 1",
"sqlState": "42000",
"index": 0,
"sql": "SELECT lastUpdated AS date, country AS country, active AS data FROM extendedData WHERE ' ORDER BY lastUpdated DESC limit 1;"
}


Any idea what could be the issues here?
When I test the endpoints in the api console I get the same response.
