Unable to generate a preview please correct the param Unable to generate a preview because of the Creative Param check failure: param asset_feed_spec[titles] must be an array. Please help me with this.
Facebook Ads requires "titles" to be an array, even if you're only using one title. The Fix: Double-check your title format: Ensure you've wrapped your title text in square brackets, like this: ["Your Title Here"]. Multiple Titles (Optional): If you want to use different titles for A/B testing, add them within the brackets separated by commas, like this: ["Title 1", "Title 2"].
This error usually occurs when there is an issue with the way the ad creative is set up in Facebook Ads Manager. In this case, it seems that the "titles" parameter in the asset_feed_spec must be set as an array, but it is not formatted correctly. To resolve this issue, you will need to check your ad creative setup and make sure that the titles parameter is formatted as an array. You can do this by editing the ad creative in Ads Manager and ensuring that the titles are entered correctly. If you are still having trouble, you may want to reach out to Facebook Ads support for further assistance. They can provide more specific guidance on how to correct this parameter and get your ads up and running successfully. Here is an example of how the titles parameter should be formatted as an array: "asset_feed_spec": { "titles": [ { "text": "Title 1" }, { "text": "Title 2" }, { "text": "Title 3" } ], // Other asset feed parameters }
Sometimes I get random errors using Facebook. Like others have said just set up the campaign again or wait some time! I guess Zuckerberg ain't that good at programming!
