Processing error Information is needed in order to combine data

[Igorpole]

Hi! I use a custom query to access API through using Web.Contents. As I have to send a POST request to get session_id (and to use it after in the same query) I can only use Anonymous option. Everything works fine in PBI Desktop, I retrieve data, refresh it, all is fine. When I publish it to PBI Service I can't refresh it. I get this error: "Processing error Information is needed in order to combine data". Any ideas about the reason?

Hi @Igorpole ,

It seems to appear that the error is because you have got different data sources with different Privacy Settings. Please reset the permissions on the Power BI Service by clicking "edit credentials" and go to Manage Gateways to set privacy settings and enter the password. Please ensure each privacy level is Organizational. Then refresh your dataset again.

Hope that's what you were looking for.

Best Regards,

Yuna

Thank you, I know this issue. I don't have any parameters in the URL. The issue is not this one.

Hi. This is tricky. Web conent won't always be refreshable. The first approach to see if you can success is try best practices from Chris Webb:
https://blog.crossjoin.co.uk/2016/08/16/using-the-relativepath-and-query-options-with-web-contents-i...

If you have change your code following that pattern and Power Bi service still can't discover the data source, then it's because it's a dynamic one:

That means you can't refresh automatically that kind of source.

Hope that helps,
