PowerBi Deep Links (URL query string parameter filtering) is not working

 If you find that your deeplinks into a PowerBi report are not working, please make sure you are using a "?" in front of the "filter parameter.

More info: Filter a report using query string parameters in the URL - Power BI | Microsoft Learn

If you are coming from a Reporting Server environment, the filter url used to have a & in front of it, which will not work.

When testing, one easy way to see if your query parameter is working is to check your filter pane. The filter if correctly picked up will show up in there in italics. The following filters the report by a field named "District" in a table named "District". The table name and column names are case sensitive. The value used for filtering is not. Another tell tale sign that your url is not correct is if the filter gets dropped from the URL once the page loads.

?filter=District/District eq 'FD - 01'

Example of an old Report Server Link which will not work because of the "&": ?rs:embed=true&filter=District/District eq 'FD - 01'

Power BI + Denodo: FailedWithUnknownOrUnsupportedDataSources

We started getting an error with our Power Bi datasets that were using a Denodo connector. This seems to be happeing only with new files and not existing datasets.

The error we were getting is:

Unable to determine the data source. In order to determine details about custom connector based data sources, Power BI service needs to connect to a gateway, however, no gateway was available/reachable. Details: Static analysis failed in gateway. gatewayObjectId:e884ca97-b4d9-45bc-8560-ad3d2d4eaa56, resultCode:FailedWithUnknownOrUnsupportedDataSources Query contains unsupported function. Function name: Denodo.Contents .

Data source for Query1

Locally the PowerBi files works fine, this error shows up in PowerBi service after you publish the dataset and take a look at the settings for the dataset.

It looks like this might be a bug in PowerBI where when you add a new query that uses the Denodo connector, it is adding an empty list to the arguments and that is causing this is.

    Source = Denodo.Contents("MyDenodoSourceName", null, []),

The problem is caused by the []. If you change the line to remove the empty [], then everything works fine!

            Source = Denodo.Contents("MyDenodoSourceName", null),
