Power BI Paginated report - Report Processing Error for subscription

[ellac]

Hi!

I have some issues rendering a Power BI Paginated Report. Background about the report:

- Data source: AAS

- Distributed in Power BI Service in Premium Capacity

- Subscriptions set to several AD groups for different sets of parameters

- The report is set to render every Monday morning

This morning four different versions of the report was supposed to run, but only two of them was successful. For the other two I got the following error message. I'm sure that I have specified all the parameters in the report.

I really don't know why I get these error messages...? My solution is to re-render the report for the parameters that got the error, in the Power BI Service, and then run it for the subscriptions - and then it works. Any ideas on why this happens? It's a bit annoying to have to do this manual rendering, when the subscriptions should work automatically. Thanks in advance!

I got a very similar error message. Solved by uncheckning "Preview Image" in the subscription settings.

Hi @v-yanjiang-msft ,

Thanks for your answer!

I understand your point, but the problem is that I don't pass an empty string, at least not on purpose. I have a theory that this problem occurs when I modify the subscription and/or the report in some way. I always rerun the report for each subscription when it's updated (modified in PBI report builder and then published to PBI service), to make sure that there are no errors with the "new" report and its parameters.

My solution this far is to delete the subscription and then create a new one and set up the subscription information all over again.

I'm so confused about this problem right now so I no longer know what the cause is and what the effect of all this is...

Anyways, thanks for your answer! I will post here if I come up with a solution.

Hi @ellac ,

By my reserch, if you pass parameter value as empty string like parameter = "" it will give you that error.

If you really need to pass a blank string as value, you can do the folowing:

• open Parameter Properties (right click your parameter on Report Data panel);
• mark the Allow blank value ("") checkbox.

Hi again @v-yanjiang-msft,

I double-checked now, and all my parameters allow blank values. And the error still keeps on coming. Any help is appreciated, this error makes me so confused...
