As you do not mention any detail, it is almost impossible to answer your question.
okay,The error I got when I clicked on the related action in dashboard called document attach.
OK. This is still not really helpful.
Can you share the config of that related action in your record? Can you share the process variable config of the called model?
Additionally, you will find much more details in your server error log. I've seen this occur for completely different situations in the past.
Check your interface(include Any expression rules inside this interface) which you are using in your process for that related action. You may have some errors in your interface (Ex missing cdt column, syntax errors)
