Hi Emre Karakuş,

You could try to write a test class to test your query and check if it works.

1,Please do synchronize on the table related to your query.

2,Refresh all cache on AOT, on AOT-> Tools -> Caches.

Hello,

I restarted many time AOS services and compiled many time Full CIL. It's still same. Do you know of any other solution method?

Hi Emri,

As per my experience this issue should be solved by running a Full CIL compilation.

Hi Emre Karakuş,

You'll get this error when you try to call a method or access a null object.

1,Please try to compile the query you need to add.

2,Go to Build -> Generate Full CIL

3,If it doesn't work, try restarting AOS.

Hope this helps.

Hi Emre,

Did you try doping a DB synch and full/incremental CIL generation?
