Quick Summary
The `DISCORD_FOOTER` error signifies that the footer component of a Discord embed is either missing or improperly formatted during the creation of a message. This results in the Discord client being unable to render the message correctly, leading to the error.
Common Causes
- Missing Footer Field: The 'footer' field is omitted from the embed object sent to the Discord API. Discord expects a 'footer' object to be present if the footer is intended to be displayed.
- Incorrect Footer Data Type: The 'footer' field is present, but its value is not an object as expected. Discord expects the 'footer' field to contain an object with 'text' and potentially 'icon_url' fields.
- Missing 'text' Field in Footer: The 'footer' object exists, but the mandatory 'text' field within the footer object is missing. The 'text' field provides the main text displayed in the footer.
- Invalid 'icon_url' Field in Footer: The 'icon_url' field is present within the 'footer' object, but the provided URL is either invalid (e.g., malformed URL, inaccessible resource) or the image format is not supported by Discord.
- API Rate Limits: While less likely for this specific error, exceeding Discord's API rate limits can sometimes lead to unexpected errors, including failures in embed rendering. This becomes more probable with bot interactions that create many embed messages frequently.
Step-by-Step Fixes
Method 1: Ensure 'footer' Field Exists and is an Object
Step 1: Examine the code that generates the Discord embed.
Step 2: Verify that the `footer` field is present in the embed object.
Step 3: Confirm that the `footer` field's value is an object, represented in many languages as a dictionary or associative array. An example in JSON format: `"footer": { ... }`
Method 2: Add Missing 'text' Field to Footer
Step 1: Inspect the `footer` object within your embed data.
Step 2: If the `text` field is missing, add it. The `text` field requires a string value . Example: `"text": "Footer Text Here"`.
Step 3: Make sure the value contains the text you want visible in the footer.
Method 3: Validate 'icon_url' Field (if present)
Step 1: If your footer includes an `icon_url` field, ensure the URL is a valid, accessible URL that points to an image (PNG, JPG, or GIF are generally supported).
Step 2: Test the URL directly in a web browser to confirm it loads the image correctly.
Step 3: Remove or correct the `icon_url` if it's invalid or unnecessary. Discord automatically caches images, so changes reflected in the hosted image will take some time to become visible.
Method 4: Implement Rate Limit Handling
Step 1: If you suspect rate limiting, implement error handling in your Discord bot or application to detect 429 errors (Too Many Requests).
Step 2: Incorporate a retry mechanism with exponential backoff. This means waiting longer before retrying after each failed request.
Step 3: Optimize your API usage to reduce the frequency of requests, such as caching data or batching operations.
Method 5: Code Review / Debugging
Step 1: Carefully review the code responsible for creating the Discord embed.
Step 2: Use debugging tools (print statements, debuggers) to inspect the structure and content of the embed object before it's sent to the Discord API. Pay close attention to the 'footer' field and its contents.
Step 3: Compare the generated embed object with Discord's API documentation and examples to ensure it adheres to the expected format.
