I am also having this problem, where I am receiving the error: " print map failed for ${ location }:{"error":{"code":500,"message":"Error performing execute operation","details":[]}}"
However, I have not included the map in my print template.
If I run the generate report button on the same selected records more than once, I get different failed objects every time (see below). It seems like it will work if I do less reports, but there is no consistency. I will try printing one report, it will give me the error, but if I try it again, sometimes it works. I have 130 reports to get printed today, so this has been frustrating and time consuming. I did not notice this problem until I added relevant statements into my print template.
