Unable to clone blocks containing Super Table fields

[jwb009]

Description

I'm unable to clone or copy/paste any matrix blocks that contain a Super Table field. I get a Server Error Occurred message. The console error: POST http://ks3.test/index.php/cms/actions/smith/field/render-matrix-blocks 500 (Internal Server Error) jquery.js:10099

Stack Trace:

 yii\web\BadRequestHttpException: Request must accept JSON in response in /Users/4319jb/sites/ks3/vendor/craftcms/cms/src/web/Controller.php:352
