# Troubleshooting 1. Upload API call returns an `Error: 102` message - The file does not exist. Double check the file ID in the API request. 2. Conversations API returns `File does not exist` error - Make sure the file has been uploaded. Verify there is no typo in the `file_id`. - Try again. 3. `1005` - User does not exist - Ensure the user is a ZRA user. - The host might not be in the list of participants. - The host does not have a ZRA license. 4. User does not have a license - Either assign a ZRA license to the user, or assign the host to a user with a license. 5. Invalid Parameter - `1001` - Include the missing field. - `1001` - The download_url is for an MP3 file, which is not yet currently supported. - `300` - Update the field with the accepted format. (i.e. `primary_language` should be `"en"` instead of `"eng"`.) 6. Expired token - Regenerate the token and upload the file again. 7. **You do not have permission** error - Verify if the S2S app owner has ZRA license and is a ZRA admin. - Verify if the account is whitelisted.
