"Microsoft.Mashup.Evaluator.Interface.ErrorException: Value cannot be null" error expand column

[jasonyeung87]

Hi,

I am currently importing entities from Dynamics CRM cloud to Power BI desktop via the oData feed. The entities I imported are Accounts, Contacts, Leads and Opportinities. Within the Leads entitiy is a column named "ownerid":

owner ID

I tried to expand that column by clicking on the diverging arrow icon. I only choose "ownerid" (though the error appears for any checked field):

Expand ownerid

After clicking on OK, I get the following error:

The text of the error is below. I was wondering what could be causing this error? Thanks!

The full  error:

Hi @jasonyeung87 

If you click beside a Record in the ownerid column, what does the preview of the Record's contents show at the bottom of your screen?

If you actually clcik on a Record, what happens?

Regards

Phil

Hi @PhilipTreacy ,

When I clicked 1 record, the preview looks like the following:

I click on the "Record" link indicated by the first red arrow (ownerid) and get the following:

There are a lot of "Error" links. When I click on one of them, I get the following:

Sincerely,

Jason

@PhilipTreacy ,

It seems that this issue affects only the "ownerid" field. I tried expanding other columns and I don't get an error. When I checked the "ownerid" field of the other entities I imported (accounts, contacts and opportunities), the same problem appears.

@jasonyeung87 , Are you using the latest version of power bi, if not make sure you are using the latest one.

Hi @amitchandak ,

Thanks for your response. I updated to the latest Power BI desktop (2.87.762.0), but the result is the same.

Sincerely,

Jason
