The esophagus is a component of the foregut of the gut tube, which is lined with endoderm. Pure esophageal atresia can occur due to failure to recanalize. (FA2020 p359) See here for slide explanation.
Here is another diagram of the esophagus and laryngotracheal tube development showing the lumen lined with endoderm covered in splanchnic mesoderm.
