The ubiquitous File not found image, explained:
This image can appear when your Applet is set up to post an image or file, but the ingredient used in the image field does not pass any data when the Applet runs. For example, this can happen if an RSS feed entry does not always include an image URL.
Here's an example to illustrate further. The Applet below is configured to post a tweet with an image each time a new RSS feed item is published. If this Applet is triggered by an RSS feed item without an image, the File not found image will be used.
If you're seeing this image often, we recommend switching to an action that is not expecting an image each time it runs, like Twitter - Post a tweet.
How to avoid the File not found image with filter code
You can skip an Applet's action when the File not found image is set to be used with the following filter code:
let imageURL = Feed.newFeedItem.EntryImageUrl;
let noImage = 'no_image_card.png';
if ( imageURL.indexOf(noImage) !== -1 ) {
Twitter.postNewTweetWithImage.skip();
}Note that this code is specific to the RSS Feed > Twitter Applet mentioned above. If you'd like to use this filter code in your Applet, Feed.newFeedItem.EntryImageUrl and Twitter.postNewTweetWithImage.skip() will need to be replaced with your trigger's ImageURL ingredient and your action's skip code, respectively.
Alternatively, if you'd prefer to assign a default image as a fallback image instead of skipping the post you can do so by following the steps in this guide.
