Hello Power BI Pros,
We call an azure function url via Web.Contents() method as following:
let
Source = (CustomerGuid as text) => let
Source = Json.Document(
Web.Contents(
"http://powebidatarefresh.azurewebsites.net/api/PBIRefreshFunction/Run/",
[RelativePath = CustomerGuid]
)
) in Source
in
Source
It works fine, but with some certain datasets (usually larger ones), I could refresh and get all the data in the Power Query Editor (Transform data) but in the power bi desktop itself I get this error:
The reason is not obvious specially that when we call the azure function with the same customer guid it works and returns the data correctly!
Thank you in advance for your help ❤️

Hi @v-cgao-msft ,
Thank you for your response, it's mentioned that 502 bad gateway issue is related to the fact that the query returns too much data, however we use power bi for showing incretemntally saved data, that means we need all the historical data and we cannot limit the refresh time frame!
