TypeError: Field prediction step failed.

[Diksha Gautam K]

We created a simple agentic workflow with a single OOB AI agent (Record Field Value Prediction) to predict the assignment group. The AI agent itself works as expected and predicts the correct AG; however, the workflow throws an error: TypeError: Field prediction step failed.

@Diksha Gautam K ,

As per my understanding, this error usually means the record field value prediction agentic workflow step didn’t actually return a valid prediction object for the assignment group field at runtime...... often because the model wasn’t trained on a sufficient or relevant dataset....there’s a mismatch between the input fields used in the agentic workflow and what the model expects....or another component is updating the same field causing a conflict....

@Diksha Gautam K  here is my 2 Cent- 

TypeError: Field prediction step failed. is thrown by the Record Field Value Prediction step (AI Agent) in a Flow/Action when the step cannot write or interpret the prediction output for the target field (e.g., assignment_group). It’s usually not the AI model As per My Understanding as AI AGENT is running fine independently—it’s the Object around it (mapping, data types, permissions, or context).

CHECK FOR:

-> Output type mismatch (example reference vs string)

-> ACL / Scope / Run As permissions
