System permissions on TW 8.3

Hi everybody,

 

I have recently switched from TW 8.2 to TW 8.3 and all my services with wrapped services are triggering errors. After checking the logs I'm pretty sure that the problem is related with the permissions for the System user, given that this is the user that tries to execute the wrapped services. I have given permissions to this System user at all possible levels: for the concrete thing, for the entire collection of things, and so on..

 

The description of the error is:

[message: Execution error in service script [Event.AnyDataChange] :: Wrapped java.lang.NullPointerException (Event.AnyDataChange#1)] 

 

Check it on the screenshot:

I share some more screenshots of the permissions that I have done to the System user:

Thank you in advance,

Pere

Hello Pere,

 

Can you confirm if the Things involved here are utilizing Value Streams? If this is the case it may come down to the permissions on the Persistence Provider that is used by the associated Value Streams.

 

Have a quick look at this community post which seems to detail a similar issue. Note that you will want to grant Visibility on the Persistence Provider utilized by the Value Streams.

 

Please let me know if this helps you out on this one or not.
