Using Image or document input (preview) - How to pass input to this field from Power Automate

Posted on by DT-16020737-0 2

I have setup an AI prompt in AI Builder using input from the new feature "Image or document input (preview)". I have uploaded a PDF file as required for testing. I am now trying to use Power Automate "Get text from GPT" action to pass the same PDF as input to the AI Prompt. However, it always return error as below when I run the Power Automate. Does anyone know who to properly pass the same PDF used in the AI Builder AI prompt using the Power Automate? I have tried using Get file content to read the PDF, followed by converting to base64 but this did not solve the problem. Any suggestion would be greatly appreciated.

"message": "{\"operationStatus\":\"Error\",\"error\":{\"type\":\"Error\",\"code\":\"InvalidPredictionInput\",\"message\":\"Unable to identify the mimetype input\",\"properties\":{\"BackendErrorCode\":\"InvalidInferenceInput\",\"DependencyHttpStatusCode\":\"400\"},\"innerErrors\":[{\"scope\":\"Record\",\"target\":null,\"code\":\"InvalidRecord\",\"type\":\"Error\",\"properties\":{\"MlIssueCode\":\"InvalidRecord\"}}]},\"predictionId\":null}"

    what get file content action did you use? Its somehow confusing because in the question youve stated
    " I have tried using Get file content to read the PDF, followed by converting to base64 but this did not solve the problem. "

    I am also facing the same problem

    Thank you for reaching out. I have found the answer.
    Just use a Get File Content action and indicate the content as PDF before passing it to the "Get text from GPT".
