Preview.Error: The type of the current preview value is too complex to display.

I created a CRM dashboard a while back, and since a few days I cant refresh the data anymore. After some research in the queries i noticed the following when selecting the 'navigation' step in the Systemusers table. 

 

Preview.Error: The type of the current preview value is too complex to display.


When selecting Source or any other steps in the existing query, they work just fine. But I'm not able to Upload or Refresh my dataset.

As almost al my CRM dashboards use this table, they all broke down at the same time. There were no updates nor changes in my Dynamics environments. 

I noticed there was a simulair issue submitted on this forum (https://community.powerbi.com/t5/Issues/Preview-Error-The-type-of-the-current-preview-value-is-too/i...

This work around works with fixing the loading/refreshing. But the issue is still at hand. Any ideas?

Your help is greatly appreciated!

Hi, 

I updated to the latest version of Power BI, but now It's not loading at all. Refreshin just get stuck with the system users table. The steps Source and Navigation seem to be the problem, as the table does load the steps after those. But with refreshing it just gets stuck at 28 kb, while other tables load normally. 

EDIT:
Problem has been solved. I reverted back to an older version of the file (using tfs) and the issue wasn't there. The only difference is a few steps in the query that change the data type of columns. Very weird, but it works now haha 🙂

Hi @Anonymous,

 

I have tested in Power BI desktop March version but not able to reproduce the issue. Would you please update your Power BI desktop to the latest version 2.67.5404.581 then test it again?
