In your documentation you wrote, that the old version is still in place, although it will not be supported for new features.
I wrote a method in C# for writing back some testresults to testrail.
After the upgrading to v3 I got the error
Missing argument 1 for DropdownField::get_validation_rule(), called in C:\inetpub\testrail\app\controllers\miniapi.php on line 685 and defined
and here are the parameters that were passed:
The request header contains Accept: application/json and ContentType = “application/x-www-form-urlencoded” .
So are there any changes, or did I miss something?
