Document Extraction inside Community Edition

The error you're seeing isn't a Community Edition restriction - it's telling you that you need more training data. All your fields have warning symbols because the AI extraction model requires more examples to learn from. To fix this, click "GO TO STEP 1" and upload additional documents that contain these fields, then label each field in multiple documents.
AI extraction typically needs at least 5-10 examples of each field across different documents to train effectively and achieve good accuracy.

Does the field need to be the same as what's in the documents? If so, what if the field name doesn't exist in the document?

It is not necessary that all the fields must be present in the documents
if the field name are not present in the document then it's not an issue, you just need to use the different types of documents while training the model for eg, You have total 15 fields, in one of the document only 5 fields are present, in other document the next 5 fields are present, while training the model, you need to capture whatever fields are present in document.

Let me try that.

Let us know if that works for you.

It worked
