### Answer
It seems you are experiencing issues when attempting to load a .txt file into the knowledge base. This might involve file format compatibility or specific settings that need to be adjusted in Vapi.
While I don't have specific details on errors related to file uploading directly from the provided information sources, here are a few common points to check:
1. **File Format and Size**: Make sure that the .txt file does not contain unsupported characters or exceed any undisclosed size limits.
2. **Uploading Procedure**: Ensure you are following the correct steps for uploading documents to Vapi’s Knowledge Base. As per the documentation, you should navigate to the appropriate section in the Vapi dashboard to upload your documents [(1)](
