Publishing a User Data Function is giving error

I have created a Fabric SQL Database. Created a User Data Function and added the connection to SQL Database in Manage Connections section of the UDF. Then I have pasted the sample code that Microsoft Tutorial has given. Publishing the UDF is giving the below error.

Unexpected token '<', "<!--# QVsM"... is not valid JSON

    Hi VivekGoli1203,

    As i have tried and implimeted below mentioned: Create a translytical task flow (https://learn.microsoft.com/en-us/power-bi/create-reports/translytical-task-flow-tutorial#test-the-sample-code)

    when i run the UDF mentioned in the docs, it gives me success message without any errors. Can you try again once replacing the default code with the code given in the documentation. there might have been extra typos mistakes have added while copying code that might result in error.

     

     

     

     

    Thanks,

      I have used the correst code from the turorial, with correct data connection to Fabric SQL Database.

      But it has given error in my tenant. But in other tenant of our organisation it worked fine.

  • Just curious that why do we need User Data Function in Fabric SQL Database?? Use Kimball methodology/ Dimensional Modelling wherever we can. ( DimTable <--> Fact Table )

      I am trying to implement write back in a Power Bi report, so as per the newly introduced translytical workflows tutorial it asked to create a UDF that takes values from report as parameters and updates them in the Fabric SQL Database.

        This write back functionlity in Power BI is not available in User Defined Functions. You should do (write back functionilty) this in DWH aka Data Lakehouse. ( in Apache Spark with Python and INSERT ) . I will give you an example:


        Writing data back to Azure SQL Database


        # Create DataFrame to insert into the Azure SQL table ( Writing Data to Azure SQL Table )
        #  
        df1 = spark.createDataFrame([('WL2456', 'Luke1293', 'Skywalker','Null','Null',-3,'Unknown','Unknown','Null')], ['DeviceID', 'DeviceName', 'DeviceDesc','OperatorName','OperatorDesc','FacilityID','FacilityName','FacilityDesc','DeviceSerialNo'])

        # Insert the rows into the Azure SQL table
        df1.write \
            .option('user', user) \
           .option('password', pswd) \
           .jdbc('jdbc:sqlserver://' + sqlserver + ':' + port + ';database=' + database, 'dbo.Devices', mode = 'append' )
           
           
        df1.show()
