PHP errors, health status issues

PHP warnings for Illegal string offset /spreadplugin.php on a number of lines between 349 and 2788. Also site health check: REST API and Loopback requests are now failing. There is no issue when I disable the plugin. I don’t know if that’s due to changes you’ve made in an update. I know some things have changed and tightened up a little due to php 7.3. I had things creep up on me too that used to be perfectly fine. You’re probably already aware of this but I figured I better bring it to your attention, just in case 🙂
