This means that your barcode input is invalid. Please make sure you're selecting the correct barcode type with the numbers in the right format.
The barcode automation can save invalid-input errors in a text field and continue processing other records. In Setup, enable Error Message Field and select a writable text field. Without a valid error-message field, an invalid barcode value can stop the run. You can also use a formula to detect invalid values and filter them out using an Airtable view.
