Custom Connector - anonymous Authentication issue

ronenbitman — Thu, 18 Feb 2021 06:16:20 GMT

hi,

I have a sharepoint excel file with a list of tickers, and i have Web.Contents() that parses these. all was great till i got to the depolying on the Web BI portal and scheduling a refresh, where the FW gave the regular issues
one of the articales i browsed suggested resolving this by creating a custom connector so i followed the guidelines

1. installed the SDK on my VS2017,

2. type the PQ code

// This file contains your Data Connector logic section SecGovFillings; [DataSource.Kind="SecGovFillings", Publish="SecGovFillings.Publish"] //shared SecGovFillings.GetSecID = (SecID as text) as text => shared SecGovFillings.GetSecID = () as text => let //Source = Web.Page(Web.Contents("https://sec.report/",[RelativePath="ticker/"&SecID])), //Source = Web.Page(Web.Contents("https://sec.report/ticker/"&SecID)), Source = Web.Page(Web.Contents("https://sec.report/Ticker/NKLA")), #"Filtered Rows" = Table.SelectRows(Source, each ([Caption] = "Document")), Data = #"Filtered Rows"{0}[Data], Children1 = Data{0}[Children], #"Filtered Rows1" = Table.SelectRows(Children1, each ([Name] = "BODY")), Children2 = #"Filtered Rows1"{0}[Children], #"Filtered Rows2" = Table.SelectRows(Children2, each ([Name] = "DIV")), Children3 = #"Filtered Rows2"{0}[Children], Children4 = Children3{0}[Children], #"Filtered Rows3" = Table.SelectRows(Children4, each ([Name] = "H2")), Children5 = #"Filtered Rows3"{0}[Children], Text = Children5{0}[Text], #"Split Text" = Text.Split(Text, " "), #"Kept Last Items" = List.Last(#"Split Text") in #"Kept Last Items"; // Data Source Kind description SecGovFillings = [ Authentication = [ // Key = [], // UsernamePassword = [], // Windows = [], Implicit = [] ], Label = Extension.LoadString("DataSourceLabel") ]; // Data Source UI publishing description SecGovFillings.Publish = [ Beta = true, Category = "Other", ButtonText = { Extension.LoadString("ButtonTitle"), Extension.LoadString("ButtonHelp") }, LearnMoreUrl = "https://powerbi.microsoft.com/", SourceImage = SecGovFillings.Icons, SourceTypeImage = SecGovFillings.Icons ]; SecGovFillings.Icons = [ Icon16 = { Extension.Contents("SecGovFillings16.png"), Extension.Contents("SecGovFillings20.png"), Extension.Contents("SecGovFillings24.png"), Extension.Contents("SecGovFillings32.png") }, Icon32 = { Extension.Contents("SecGovFillings32.png"), Extension.Contents("SecGovFillings40.png"), Extension.Contents("SecGovFillings48.png"), Extension.Contents("SecGovFillings64.png") } ];

3. ran the code and although & set the authentication as anonymous

// Use this file to write queries to test your data connector let //result = SecGovFillings.GetSecID("GOEV") result = SecGovFillings.GetSecID() in result

4. ran the code again but was still reciving an error as authentication was not succeeding.

then i went and tried to deploy and check maybe its an issue with VS

1. i copied the file to the Custom connector folder

2. open Power BI Desktop

3. added a new data connector

= SecGovFillings.GetSecID()

the athentication window showed up, selected anonymous and it kept showing up as if it wasn't correct

the website i am trying to reach is opening regularly on browser https://sec.report/Ticker/frx

next, i tried creating a regular PQ

1. i added the code,

let Source = Web.Page(Web.Contents("https://sec.report/Ticker/NKLA")), #"Filtered Rows" = Table.SelectRows(Source, each ([Caption] = "Document")), Data = #"Filtered Rows"{0}[Data], Children1 = Data{0}[Children], #"Filtered Rows1" = Table.SelectRows(Children1, each ([Name] = "BODY")), Children2 = #"Filtered Rows1"{0}[Children], #"Filtered Rows2" = Table.SelectRows(Children2, each ([Name] = "DIV")), Children3 = #"Filtered Rows2"{0}[Children], Children4 = Children3{0}[Children], #"Filtered Rows3" = Table.SelectRows(Children4, each ([Name] = "H2")), Children5 = #"Filtered Rows3"{0}[Children], Text = Children5{0}[Text], #"Split Text" = Text.Split(Text, " "), #"Kept Last Items" = List.Last(#"Split Text") in #"Kept Last Items"

2. got the athentication window, selected anonymous

it worked on the regular PQ!

so it didn't work on VS, my custom data connector didn't work but PQ on desktop BI worked with the same PQ code (attached)

btw my custom data connector started working after the PQ code worked

how can i resolve this?

Hi @ronenbitman ,

Your custom connector project can't run in VS but it can run in Power BI Desktop?

Please provide screenshot of the relevant error message.
