Invalid data source credential - Data gateway

[Anonymous]

I am refreshing my datasets through the personal data gateway. After publishing my report, When I go to the Datasets for refreshing, it gives me an error invaild data source credential. When I go to the data set settings data gateway is working fine and connected but in the data source credential OAuth is missing, sometime it does not show me anything but sometime it shows only anonymous and windowimporsination. which gives me the same invalid credential error.

I have python model code in the report and I am using the model output to build report but I am using sharepoint folder or powerBI dataflow to input data in the python model. I think that making issue. I changed my system password, update powerBI version and Data gateway, try to input new password in the report dataset and query But nothing seems to be working.

When I connect only powerBI dataflow and sharepoint report with gateway it works fine. only with python code it gives me trouble.

Is there anything which I can do to connect the data and refresh through the personal data gateway.  Please suggest me some soultion of this. Thanks.

Hi vikassingh49111,

According to your description, it seems that when you use python code, the gateway won't work, right? If so, and if possible, could you please inform me your python code? Then I could test this in my environment.

By the way, Install the Personal Gateway - you need a Personal Gateway installed on the machine where the file is located, and where Python is installed. You could refer to Data Gateway Configuration for Python for details.

Best Regards,

Also this remove all types of sharepoint connection from other files too, the moment i publish the report from PowerBI desktop to online powerBI.

I tried to install personal gateway at the same location where my python is installed on my local computer, and I saved my .pbix powerBI file at the same location but still it showing me the same error.

The Python script I am using is - 

# 'dataset' holds the input data for this script

import pickle
loaded_model = pickle.load(open(r"Y:\ML Models\XGBVWF.dat", "rb"))
df = dataset
y_pred = loaded_model.predict(df)
df['prediction']= y_pred

and advanced editor query is - 

let
Source = SharePoint.Files("XXXXXXXXX", [ApiVersion = 15]),
#"ContractTerminationstoPredict.csv_XXXXXXX/ML Test/" = Source{[Name="ContractTerminationstoPredict.csv",#"Folder Path"="XXXXXXX/ML Test/"]}[Content],
#"Imported CSV" = Csv.Document(#"XXXXXXX/ML Test/",[Delimiter=",", Columns=4, Encoding=1252, QuoteStyle=QuoteStyle.None]),

#"Run Python script" = Python.Execute("# 'dataset' holds the input data for this script#(lf)#(lf)import pickle#(lf)loaded_model = pickle.load(open(r""Y:\ML Models\XGBVWF.dat"", ""rb""))#(lf)df = dataset#(lf)y_pred = loaded_model.predict(df)#(lf)df['prediction']= y_pred",[dataset=#"Changed Type"]),
df = #"Run Python script"{[Name="df"]}[Value],

The error message is -
