I have a snippet template that is used within a page template that selects the snippet items to display via an auto slot query.
In regular Preview mode this works fine and it’s also fine when setting sys_authtype=101 or context=1 on the preview URL.
However when it is actually published none of the snippet content is there. Instead we get an error message like this in its place.
“Problem assembling output for item: 3-101-12232 with template: mdaSnMultimedia1 exception: item definition must not be null see log for stack trace”
Any idea as to why this might be happening?
