Recently I have started seeing that, AEM author starts throwing JS error and doesnt load any component. Starts happening after a few deployments. Needs a restart to bring it back to normal. Screenshot attached. Anyone else facing this issue?
Check if any of the custom client lib is having OOTB client lib categories. If we use OOTB categories, the custom js will be included as part of OOTB js and if the custom js is having any error, that might break the complete authoring interface.
