AI Functions error for text analysis

[julianparedes]

Hello! I'm having an AI Function problem. I'm using de AI.Functions.PostProcess function, using de ScoreSentiment text analysis. This is the error message:

DataSource.Error: Se produjo un error al leer datos desde el proveedor: 'Invalid stream provided.' Detalles: DataSourceKind=AIFunctions DataSourcePath=AIFunctions DataSourceKind.2=AdoDotNet DataSourcePath.2=AI.Provider/

This is the function used:

= AIFunctions.PostProcess(Table.AddColumn(identidaddigital_surveys, "Score sentiment", each #"Score sentiment"([comment], "es")), "Score sentiment", "CognitiveServices.ScoreSentimenttexttext") meta [FunctionBrowser="TextAnalytics"]

I am using the Versión: 2.144.1378.0 64-bit (june de 2025)
Please, I hope you can help me with this issue. Thanks!

@julianparedes  Seems like AI.Functions.PostProcess is no longer available. Please refer the community thread below for the same. I hope this may answer your question.

Thank you! Can I use the Azure AI Language services with an User Premium License?
