Hi,

After I upgraded a local solution to 9.13.1 and start up the app pool I get an error saying "Data is Null. This method or property cannot be called on Null values."

Looking at the stacktrace you can see that its somethinh with the startup.

[SqlNullValueException: Data is Null. This method or property cannot be called on Null values.]
   System.Data.SqlClient.SqlBuffer.get_Boolean() +2925525

   System.Web.SyncEventExecutionStep.System.Web.HttpApplication.IExecutionStep.Execute() +142
   System.Web.HttpApplication.ExecuteStepImpl(IExecutionStep step) +75
   System.Web.HttpApplication.ExecuteStep(IExecutionStep step, Boolean& completedSynchronously) +93

I have stripped out our custom code and replcade our web.config with the one from the release package. I have tried to lower the version numbers to force a "rerun updates".

Any ideas?

Regards / Aki

Hi,

Good catch! I was able to reproduce the bug on one my test solution. The cause seems to be related to not possibility to render content output by 'LastAndFound' feature (at least in my case). I've submitted task 6740 to fix the bug. Workaround is downgrade the solution (e.g. to 9.13.0), find 'LostAndFound' folder(s) in content area(s) and delete it in regular way. Upon it's performed the moving to 9.13.1 is done correctly. Please, comment your results.

Hi,

Thanks for the input. I'll try it. Even though I checked the page table and saw the 'LostAndFound' page and saw the it had nulls in some bit fields so I deleted it from the database but it reappeared when I recycled the app pool. But maybe it works if its deleted from the backend.

Hi,

Yup, you should delete the content using backend but not from database directly.

Hi again,

Downgrading to 9.13.0, deleteing the "LostAndFound" and the upgrading to 9.13.1 seems to have done the trick.

Thanks for your fast response.
