Good day, We have deployed Customizer Lite in our test environment and would like to test customizations. Unfortunately, however, the following dialog box is displayed when saving a Customization in /appreg.
I have not tried, but have you checked the logs of the MongoDB container and of appreg container?
:D I checked the customizer lite package. It does not start a MongoDB. So, I wonder how it stores its configuration. The full package for Customizer is using MongoDB for all settings. I think you need to open a case and ask.
