PBI app cannot load odata.feed with M functions in the URL

Hello,

I have built an report where the source is odata.feed with an M function in the URI (to filter requierd data before downlaoding). For example a source request like

= OData.Feed("https://services.odata.org/northwind/northwind.svc/Customers?$filter=PostalCode ge '" & Number.ToText(12209) &"'", null, [Implementation="2.0"])

In PBI Desktop this works. When it is published to web , you cannot update the data under settings/datasets and the PBI web side displays the following error

Query contains unsupported function. Function name: OData.Feed

As far as I have tested, the problem occurs with all M functions. By replacing Number.ToText(12209) with "12209" the PBI app has no problem and the update the request accurately.

Is there a way around this problem, or am I doing something wrong?

Kind regards

Jonathan
