Power Automate AI Builder Error

[busekara]

Hi Everyone, I have created a model using Form Processing Using AI Builder, when tried to run this model it is giving attached error. can someone help me on this please. 

Error message is:

{"operationStatus":"Error","error":{"type":"Error","code":"InvalidPredictionInput","message":"The base 64 binary content is missing for input single","properties":{"BackendErrorCode":"InvalidInferenceInput","DependencyHttpStatusCode":"400"},"innerErrors":[{"scope":"Record","target":"single","code":"InvalidRecord","type":"Error","properties":{"MlIssueCode":"InvalidRecord","MlIssueTarget":"single"}}]}}

Hi @busekara,

Thanks for posting about this. It looks like you are building a interesting automation around AI Builder and Teams, let's get you unblocked. 🙂

• Does the email that is being processed by the flow contains a signature? If so, you will need to filter the signature out so it's not processed by the model. More info on how to do it: https://docs.microsoft.com/en-us/ai-builder/form-processing-model-in-flow#filter-email-signature-fro...
• Are you getting this error while testing the flow using the manual Test option that is on the top right of the flow editor? If so, there is currently an issue with the manual test option for emails. You can try the flow instead by sending you an email so the flow gets triggered.

Also, as a recommendation we now have dedicated AI Builder connector, so no need to use the Predict action on the Dataverse connector.

Let us know if this solves the problem!

Hi, 

Thank you very much for your answer. My problem was solved by using the connector you suggested.

Morning all

Found this page as I'm having the same issue. I'm working through the same MS Learn module as the OP and have run into the same issue. However, I've followed your guidance here @JoeF-MSFT and am still getting the base64 error. I've switched over the new AI connector as you advised, and also added the inline processing condition for signatures re your link, but no joy? I've also tried outwith the Test funcionality, but same thing. Not allowed to upload image apparently, so link here: imgur.com/a/1uZRPs3 

My test sender is gmail and it appears to be sending as a multi-part HTML. As we can see, base64 encoded..

Any ideas? Thanks

Also tried as this, but same outcome: https://powerusers.microsoft.com/t5/General-Power-Automate/InvalidPredictionInput-amp-quot-amp-quot-...

Thanks for reaching out @andyinv Let's get you unblocked. 🙂

Did you set these fields to Yes in the Outlook trigger as in the screenshot here?

Also, how are you testing? By sending an email or by using the Test using previous run feature?  You should test by sending an email.

Argh... somehow, in all my various tests between trying things, I hadn't turned on the Include Attachments and Only Attachments. I can't believe it was something so simple and I missed it... especially when I was following the green arrows below it.

Nightmare! But thanks loads for the quick reply, really appreciate it.

On that topic tho, are there any plans to update the MS Learn modules to take current tech into account? It was following that initially that I think kinda led me into this mess of google searches, trying everything and anything...

As you're probably aware, the docs use the legacy Predict module:

https://docs.microsoft.com/en-us/learn/modules/implement-power-automate-ui-flows-ai-builder/4-use-po...

Thanks!

[JoeF-MSFT]

Good to hear you got it working @andyinv!

Yes, indeed we need to update that module. 😉

hi @JoeF-MSFT ,

I also have problems with running the AI Builder at the moment.

My scenario is "extract information from forms"....

- I verified that the attachments don't contain a signature or are locked

- I tried to send the test mail "externally" to the test area, he recognizes the attachments but he fails the recognisation.

I'm sending you a screenshot of the flow. The only different compared to a "classic" one, is that I apply a condition filter, The AI process has to run only for a file which complies with a certain rule (e.g.: the filename contains a keyword)

Thank you for your help!

[JoeF-MSFT]

Hi @Anonymous - thanks for asking.

Instead of 'current Item' for the Form input in the Extract information from forms action, try selecting Attachments Content.

hi @JoeF-MSFT ,

thanks, it solved. Actually i did an attempt with it, but probably didn't reset the script in time for it to process. I tried after 24 hours, it seems to work, now I have only to understand how to extract the actual values in an array :D.
