My sandbox enviroment https://allnieuw-sandbox.mxapps.io/ has an event that refreshes the page every 30 seconds. It does that correct a few time, but after a while it will respond in an unexpecterd error. The log file says: 14:47:16runtime-container/2vrd7ERRORClient:14:47:16runtime-container/2vrd7Error14:47:16runtime-container/2vrd7at PS (https://allnieuw-sandbox.mxapps.io/dist/Dtmj65WC.js:53:32569)14:47:16runtime-container/2vrd7at async https://allnieuw-sandbox.mxapps.io/dist/Dtmj65WC.js:65:1264814:47:16runtime-container/2vrd7at async https://allnieuw-sandbox.mxapps.io/dist/Dtmj65WC.js:53:3371614:47:16runtime-container/2vrd7at async t.Sunday (https://allnieuw-sandbox.mxapps.io/dist/Dtmj65WC.js:53:33320)14:47:16runtime-container/2vrd7at async fR.retrieveByXPath (https://allnieuw-sandbox.mxapps.io/dist/Dtmj65WC.js:65:3908)14:47:16runtime-container/2vrd7at async https://allnieuw-sandbox.mxapps.io/dist/CMOIuwah.js:1:5394Nothing of this sounds familiar for me.
