There is a json file that is sent to the database via a php script and written to one of the cells. I get the same error from time to time:

[Mon Feb 14 02:38:00.632563 2022] [php:error] [pid 8316:tid 12364] [client *****] PHP Fatal error: Uncaught mysqli_sql_exception: 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 '\xd0\xba\xd0\xb5\xd0\xb9, \xd1\x81\xd0\xba\xd0\xb0\xd0\xb6\xd1\ x83 \xd0\xbd\xd0\xb0 \xd0\xb1\xd0\xbe\xd0\xbb\xd0\xb5\xd0\xb5 \xd0\xbf\xd0\xbe\xd0\xbd\xd1\x8f\xd1\x82\ xd0\xbd\xd0\xbe\xd0\xbc \xd1\x82\xd0\xb5\xd0\xb1\xd0\xb5 \xd1\x8f\xd0\xb7\xd1\x8b\xd0\xba\xd0\xb5, \xd0 \xbf\xd1\x80\xd0\xb8\xd1' at line 1 in C:\Apache24\htdocs\Loc\Php\VstavitJson.php:14\nStack trace:\n#0 C:\Apache24\htdocs\Loc\ Php\VstavitJson.php(14): mysqli_query(Object(mysqli), 'UPDATE LeagueOf...')\n#1 {main}\n thrown in C:\Apache24\htdocs\Loc\Php\VstavitJson.php on line 14

Russian letters may appear in the json file itself. It seems that the error swears at them, but I do not understand how to fix it. Does anyone have any ideas?

VstavitJson.php code:

if (isset($_POST))
    $id= $_POST['id'];
$sql= "UPDATE LeagueOfDreamers SET histjson= '$histjson' WHERE id= '$id' ";
if (mysqli_query($db, $sql))
   echo "histjson updated successfully";
   echo "Error updating record Json: " . mysqli_error($db);

before inserting data into the database, the data itself must be escaped.

Check the encoding in which you send json to the server and the database encoding.

Check the CHARSET of the server, client, connection... add the required SET NAMES to the additional connection commands.
