Algorithm not allowed in file

[NomiasSR]

I'm trying to decode a jwt token using this command on my Laravel application:
$decoded = JWT::decode($access_token, $my_secret, array('HS256'));

but I'm having this message error all the time:
UnexpectedValueException: Algorithm not allowed in file C:\myserver\vendor\fproject\php-jwt\src\JWT.php.

When I use the same token on site jwt.io, the token is correctlly decoded. I'm doing everything based on documents on your site.

Any ideas about what is happenning here?
