After I select Document Type from Transactions on MWS as Query field, MWS throws java.lang.NullPointerException like shown below. Anyone help ? (Version 10.3)
java.lang.NullPointerException
Hi Mehmet,
Could you check on the full.log in your SAG file directory? You should able to view full error message.
May I know any changes had done in your environment recently?
Thanks
Kind regards,
Alex Foo

Not an TN /MWS expert , but a NullPointer Exception usually indicates incorrect handling by the application when there is missing data. Would suggest you raise a support ticket mentioning products installed as MWS /TN
-NP
UPDATE!!
When I run wm.tn.doctype:list service with refresh parameter = TRUE ,
It works for a time being about 10 mins then it keeps getting error and need to run the service again.
So any suggestions ?
