# Fix Interaction Did Not Respond

> How to fix the "Interaction Did Not Respond" error on your Discord bot.

> TL;DR: In most cases, the error can be fixed switching from a send message block to a interaction reply block.

There are two possible errors relating to interactions not responding:

> This flow is missing a \`Interaction Response\` block. Please add one to customize this message.

> This application did not respond.

These errors happen when you have a flow triggered by a Discord interaction (e.g. slash command, modal, button, etc.) but you aren't actually responding to that interaction. Discord requires that all interactions (slash commands, modal submissions, button presses, etc.) have an **interaction response** of some kind.

This most commonly happens with slash commands, when you use a **Send Message** block rather than a **Text Reply to Interaction** block. This causes the interaction to get no response, although your flow will otherwise work as expected.

In cases where you want to use a standard message send (like creating a giveaway), you can add a basic "Done!" or "Giveaway created!" interaction reply. You can even tag it as Ephemeral so it only shows up to the person who ran the command.
