How to resolve 'InvalidTemplate' error in Power Automate for AI Builder text recognition flow?

Qureshi, Shahraiz S 0

I'm experiencing an 'InvalidTemplate' error in a Power Automate flow utilizing AI Builder for text recognition. The error message is: "The template language expression 'body('Predict')['body']['predictions']' cannot be evaluated because property 'body' doesn't exist." The structure seems to reference non-existent properties. I've followed the guide on this page. How can I correctly reference the output from the 'Predict' action to avoid this error? Any guidance is appreciated.

Module: Build a Power Automate flow with AI Builder Text recognition

Please follow the steps outlined in Unit 3 to create a Dataverse table for storing recognized text. Next, create a flow in Power Automate that triggers AI Builder Text recognition whenever an image is added to your OneDrive. Save the result in the table you created. Afterward, set the folder for Power Automate to monitor for new incoming images as shown:

We tried it on our end, and it worked perfectly. Please refer to the screenshots below:

That approach does not work. What happens when you run the flow? The problem occurs during execution. Additionally, the 'For Each' component changes when I press save. When you run the flow does it have an object or a array? Please post the finished flow. I would like to see. The problem occurs when you run the flow.

The issue occurs when you run the flow. Can you share the finished screen shot? does it give you an array or object foreach loop? See images for more information.

Hi Qureshi, Shahraiz S,

Thank you for your patience.

The issue with the 'For Each' component changing when you press save might be related to how the flow is interpreting the data type of the input. Ensure that the expression inside the 'For Each' correctly references an array or a collection of items. If the structure of the data changes, it might cause the 'For Each' to behave differently.

If you are still facing any issue, please let us know in the comments.

I have a couple of follow-up questions to help us better address the issue:

When you run the flow, do you receive an array or an object as the output?

I have ensured there are no errors, and it indicates that I can test it. However, I am still experiencing issues.

Could you please provide a screenshot of the flow running successfully? This would greatly help me understand what might be going wrong on my end. In the flow checker I have no errors it's just when I run it. Does the predict faction output an array or and object for you?

Additionally, I believe the walkthrough might need to be updated to reflect the correct process.

Thank you for your support and patience.
