failed to get dynamic schema

[JohnEl]

Hello,

I build a prediction model whose entity is fed every hour by an Excel file on OneDrive. It works very well.

I'm trying to build a flow from a solution with Power Automate so that a user can run my prediction model from a PowerApps application with a click of a button.

However, when I select my prediction model, I get an error message: Failed to get dynamic schema (translation). Any idea to solve this problem? Thank you.

hi @JohnEl  do you share your model with the person who need it?

Hi John,

Have you trained your custom model and published it?

There are below prerequisites to use AI Builder in Power Automate:

1. you will need to create the flow inside a solution. More information: Create a flow in a solution.

2. it must be a trained AI Builder model or an AI Builder prebuilt model

Hi John,

Have you added you trained "AI Model" to the CDS Solution from where you are creating your Flow?

Hello kestenholz, ChristainAbata, EricaBao,

Sorry for my late response and thanks a lot for your feedback.

My solution with Model : https://www.ve-studio.net/BorneoSolution_1_0_0_1.zip 

The error is located in the flow "PowerApp -> Predict"

.

Yes the prediction model has been trained and then published into a CDS solution. I manage to create an application controlled from this model and read the prediction data.

However, I would like to be able to run my model from a canvas application with a flow. To this end, I create a prediction flow in a solution and also integrate my model and my entity into it. In my flow, the error message appears when I call my custom prediction model.

the error message does not appear when I call a prebuild model such as:
- RecognitionText
- BusinessCardModel
- KeyPhraseExtraction
- LanguageDetection
- SentimentAnalys

Thank you so much.

Bonjour @JohnEl ,

Your topic is 2 years ago, should you remember the solution for it? I'm having the same problem... desperate in search of a clue...
