Classifying Error Messages When Uploading Documents

Updated on April 6, 2025

This is a guide that summarizes the error codes that can occur while using the Alli system and the corresponding actions to take. Errors are largely divided into two types: those that the member (the person uploading the document) can resolve themselves, and internal system errors that require help from an Alli account manager. Please refer to the table below and take the appropriate action for your situation.
