Hello Support,

I'm running into this situation (System.NullReferenceException: Object reference not set to an instance of an object
) couple of times every day.

We have more than 50 different scripts; every other test has coded steps. All the scripts are working as expected.

But, while running scripts for some reason (say after 20 scripts) we closed browser forcefully it throws below exception. Now, we are using QA SP2; but I see same issue since long time. I’m expecting to see Failed -15 Passed Out of Total 20 executed.

Finally, we are ending up with Failed - 0 passed out of Total 0 executed.

Screenshot attached.

Is there any way to solve this issue?

Your help is really appreciated.

Thanks,

Madhu.

Hi Madhu,

Thank you for writing.

I looked at the screenshot and tried to reproduce the issue but I did not managed to reproduce this issue. Could you provide us a demo project that reproduces the issue. This will help us to investigate it and to give you appropriate help. I am looking forward to you reply.

Hi Dobry,

Thanks for support.

Sorry, our application is intranet based outside access is difficult! This morning while updating one of the custom script I see attached error.
C:\TrunkBuildScripts\Fixed Income Trades\Fixed-Income Trade-Buy.aii.vb: Line 47: (BC42104) Variable 'ExpAccruedInt' is used before it has been assigned a value. A null reference exception could result at runtime.
I hope this error will give you more idea? But as showed in screenshot (error) I have not declared same string more than once.

Thanks,
Madhu.

Hi Madhu,

(Dobry is on vacation this week).

To understand what is causing the "Variable 'ExpAccruedInt' is used before it has been assigned a value" we need to see the code involved. Can you send me these files (put into a .zip first):

Future Trades Entry-SLLCL.aii
Future Trades Entry-SLLCL.resx
Future Trades Entry-SLLCL.aii.vb

Once we receive those we should be able to figure out what is causing this.

Best wishes,
