@CF Team
I'm sorry to hear that you're experiencing issues with uploading files to your knowledge base. To assist you better, could you please provide me with the file format you're trying to upload and confirm if the file size is within the allowed limits? Additionally, please ensure that the file is not corrupted and that you have the necessary permissions to upload files to the knowledge base. If everything seems in order on your end, there might be a temporary issue with the service, and I would recommend trying again after a short while. If the problem persists, please ask support for more info on this.
