The error message "failed to parse body" usually means there is a formatting issue in the "Body" section of your HTTP API enrichment. Common causes include missing quotation marks, extra commas, or improperly formatted special characters. To resolve this, ensure all text is in double quotes, remove any extra commas, and double-check your data format. You can also use a JSON validator like JSONLint to check your formatting before sending the data.
Could you please copy and paste the JSON or body content you're using so I can help troubleshoot the specific issue?
