Your problem
My problem is: This error occurs when I am designing a Mautic template through its visual builder. If I add Dynamic Content where the condition is through a multi-selection custom field, when exiting the builder and clicking on ‘Save’ or ‘Save and close’, the changes are not saved, that is, the Dynamic Content is not saved.
These errors are showing in the log: The logs do not save any errors, as the problem occurs at the Javascript level in the web browser.
Steps I have tried to fix the problem: In the following video, we can see how I add Dynamic Content with the builder, and how, when clicking on ‘Save and close’, it does not save and the screen does not close. https://www.loom.com/share/26e4a730d9d347579814df6633743a11?sid=cca45a40-89af-4659-9498-09cb5438ccfb
