validation rules doesn't work in Blueprint when it is validated using function?

validation rules doesn't work in Blueprint when it is validated using function?

I have tried to create a validation rule in the deal module. it works if I try to create a deal manually or if I try to update the empty field inside a deal. 



but when I try to update the field via the blueprint mandatory field, it seems the validation rules doesn't work, like this:




here is the code I use

  2. entityMap = crmAPIRequest.toMap().get("record");
  3. markingCode = entityMap.get("Marking_Code");
  4. response = Map();
  5. if(!markingCode.contains("/"))
  6. {
  7. response.put('status','error');
  8. response.put('message','Your marking code is written in the wrong format');
  9. }
  10. else if(markingCode != markingCode.toUpperCase())
  11. {
  12. response.put('status','error');
  13. response.put('message','Marking code should be written in the UPPERCASE letter');
  14. }
  15. else
  16. {
  17. response.put('status','success');
  18. }
  19. return response;
