AI Document Center Classification Model - "Unsupported file type" when uploading .eml file

Hi everyone,

I am working with AI Document Center in Appian and I am trying to use a classification model with an .eml file.

According to the documentation, .eml should be a supported file type, but when I run the model I get this error:

Generative AI
Classification: Unsupported file type. Try again using a supported type or contact your admin if the problem persists.

The issue happens specifically when I upload an .eml file

Has anyone successfully used .eml files with AI Document Center classification?
