Data Refresh not working with Web data

I understand from a support article about data Refresh that Web is among the supported datasources for refresh.


I have a complex dashboard with 5 web datasources retrieving JSON data from REST web services with a lot of M transformation.


I can get the App to refresh manually or setup a schedule refresh


I get the following error.


Can you provide feedback/help?

I have run into that error with Web Queries when I try and either leverage parameters or reference other queries in the query set. So things like paginating, and dynamically generating your URLs wouldnt work.  

I'm not on the Power BI team, but I would assume they keep these kind of things from working because it could be a big resource hog if you are dynamically generating urls and the query never stops. 

Does that sound similar to what you are dealing with?

I'm suprised Excel based Web data is not supported.





The M-code calls Excel.Workbook......


    Source = Excel.Workbook(Web.Contents(""), null, true),


Anyone know if this is on the roadmap?




Awesome. Those two blog posts of Chris helped me find the solution:

a combo of relative path and passing along the parameter using Query.

After publishing the .pbix file, I had to set the credentials on the data set to Anonymous as well.

(I pass along an API key in the function itself)

I'm having the same issue.


Have anybody solved it?

I am experiencing the same issue. Has it been solved?




I've experienced the same issue doing a function to query multiple SharePoint lists using the REST API. Per support on Thursday this week, service related issues should be logged via the Office 365 Admin Service Ticket interface. Only desktop related issues can be logged via the Desktop send a frown. 


I still don't have a resolution but am working with them on Monday. I'll let you know if I figure it out.

@dcohendumani First check whether manula refresh in your source file works properly. If not there is no point in scheduling refresh. But if you are using REST then why to schedule refresh when its already getting LIVE real time data using your web service created ?

Manual refresh from within the powerbi app does not work. It says refreshing and it stops

If you used Power BI Desktop to publish the file, I would suggest trying out the below.

Use the browser  Get Data->Files->Local file and upload the .pbix file and then see if the schedule refesh page gives you option to specify the setting.

I tried this already but still no luck. Keep telling me that the data soruce does not support refresh. I think this may related to the complexity of M transformation in the data source. I am using some recursive function to query pages of dataset using REST. It refreshes fine in the Power BI Designer/Desktop or from Excel but not fro within the PowerBI app?


I have 5 queries in my pbix file, I am goint to try to isolate which of the query is causing the problem.

There have been a lot of issues with "supported" data refreshes not working. However they do appear to be getting fixed. I had an issue with SharePoint Online OAuth2 settings seemingly not saving but this was recently (like as of today) seemingly fixed. I currently have an issue where I can refresh a file that is local but not on a network share. Bizarre stuff. I recommend that you use the smiley face icon, give a rating (doesn't matter) and on the feedback form that is presented, take a screen shot of the error and report what you are trying to do. I get nice emails back from people like Kevin when I do this that follow-up on the matter.

@ me in replies or I'll lose your thread!!!
