Understanding the Issue

The default response is triggered by a fallback handler that activates on file uploads before the attachment-handling topic fully activates. This results in two responses: the default ‘I received the file you sent, but I currently can’t process uploads…’ message, followed by the intended ‘Thank you for attaching your document. Would you like me to proceed ahead with the analysis?’ response.

The root cause of this issue is the default fallback handler that is triggered on file uploads. This handler is designed to provide a generic response when the system is unable to process a file upload. However, in this case, it is causing conflicting messages and a poor user experience.

Solution

To suppress the default response, teams can configure their platform’s topic or dialog flow to include a dedicated ‘attachment received’ transition or input handler. This handler should intercept uploads early, preventing the default message and routing directly to the custom analysis prompt.

For example, in Salesforce Agentforce, teams can edit their attachment-handling topic in Agent Builder to prioritize it via input validation or guards. They should ensure the topic classifies uploads first by testing prompt specificity, and disable generic fallback instructions in agent settings.

Agent Builder Configuration

// Example configuration code
// Input validation
if (input.type === 'file') {
  // Route to custom analysis prompt
  topic.transitionTo('analysis-prompt');
} else {
  // Handle other input types
  topic.transitionTo('default-prompt');
}

Testing and Verification

To verify that the solution is working as expected, teams should preview the topic with sample image uploads to confirm single-response flow. If persistent issues occur, they should check global settings for upload fallbacks and override with topic-level handlers.
