An error occurred while rendering the report

[lauravd]

Hi, 

I get an error message once trying to open my report. Unexpected Error. An error occurred while rendering the report. 

Followed steps below, but it didnt help. Please advise. 

1) Close all instances of Power BI Desktop

2) Open file explorer and navigate to the folder <system drive>:\Users\<user>\AppData\Local\Microsoft\Power BI Desktop\CEF\cache

• replace <system drive> with your operating system hard disk partition
• replace <user> with your user profile name, typically the alias you login to Windows with

3) Delete all contents of this folder

4) Restart Power BI Desktop

Thank you,

Laura

Hi @lauravd,

1. Which kind of desktop version do you run? Please update to the latest version then try again.

2. When you try to open other reports, does the same issue occur?

3. Please open the same report in desktop on another machine.

4. Please open the Power BI desktop firstly, then File->Open to open the report to see if the same issue occurs.

Best Regards,

Hi,

I am using 32bit Desktop version. Had the most recent (December) which I downloaded on Friday and the this issue started. Other reports are working, and this one was working as well as I was running it successfully for the las two months. I tried to open it as per your suggestion File-Open, but still the same. Finally I downloaded October version of PBI desktop (November version was playing funny as well) and it works. Please advise.

thank you

Hi @lauravd,

As you can open the report in Power BI desktop October version, please save the report from October version then open in the latest desktop to see if it works. 

Did you import the data model to the report? If it's not live connection or DirectQuery, would you please share the pbix file with us? You can upload it to your OneDrive and sent the link to me via private message. 

Best Regards,

Has this issue been resolved yet? I am facing the exact same problem

[lauravd]

Nope, I am still experiencing this issue with December version of Power BI.

Hi @lauravd,

Would you please review my previous post? As the issue happens to one specific report, if it's not DirectQuery or Live connection, would you please share pbix file with us? 

@antonyp Did the issue happen to one report or all reports on your side? 

Best Regards,

Thank you.

I noticed that removing a few columns from the table got it to render properly with the latest power bi desktop. In my case, the table has quite a few columns, but this was working fine with the previous version of the dektop. Please check if the new Power BI desktop has any issue with tables with many columns

[lauravd]

My table contains only columns that I use in my report, so can't get rid of any of them.
