I have written an automation rule where we create 10 different child issues and assign to different departments when parent issue is created. I am getting an error while creating child issues where the summary exceeded 255 characters limit. For creating child issues I am appending 10 different categories names to the end of the "SUMMARY field".
Example - The summary for each child issue are appended with the {{ Summary of Parent issue+ department name }}.


If the summary field has exceeded 255 characters limit then the child issue is not created, where as the parent issue is created.
I have attached the screen of the audit log and the automation rule.
Is it possible to validate the length of the summary and truncate it to 255.
Thanks & Regards,
Muru.
