Calendar View throwing Null exception error.

Question

Hi everyone,

Recently migrated from on premise to online. When trying to create a new view or modify the migrated view it is throwing the null exception (Object reference not set to an instance of an object.).

I have checked for the count on the view, it is 3000 records and less than the 5000 limit that microsoft have.

The issue i am facing is, i have a category choice column for calendar list. Trying to create a view applying filters where Category is "pw" and created is greater than 1/1/2023 ( which has 3000 count records).

Now it throws me error everytime i try to create a view for this filters. After lots of trail and error i got records on the calendar when when Category is "pw" and created is greater than or equal to 4/2/2024. If I had greater than equal to or less than 4/1/2024 it would start throwing error. which is weird.

I would appreciate if anyone is facing this error and found a solution for it.

Thanks

Dear Ashok Kumar Masetty,

Good day! Thank you for posting to Microsoft Community. I am happy to help you

I created the list directly in SharePoint, but I didn't have the same view issue.

 I also noticed that you have collected the relevant Ids, so I suggest that you contact Microsoft's support and give them this Id to ask them to investigate further for you if there is a problem on the server side. You can raise a service request in Microsoft 365 admin center, which the support there has the related permission and resource to help you check from the backend

Thanks for your cooperation.

Tim, can you please suggest me any more scenarios on why this would throw up an error?

Also if you are able to replicate it on your end.

Thanks

Tin,

thanks for your reply.

I have created the list first and then migrated the whole content this time. The issue remains the same.

I am getting Correlation ID: 97a021a1-207c-0000-0711-7850a36bc180.

weird thing is i get records for some views only after 4/2/2024, any day i use ends up erroring out. Even though the entire category items for that view are 1500 i don't get the view to work.

I noticed that you did a data migration, in order to check if SharePoint Online is causing this phenomenon first, could you please try to create a list directly in SharePoint to test it.

I look forward to your reply. Thanks for your cooperation.
