Welcome to the community, @bricevkarickhoff! Your survey project should have a question (either a select_one by0xe03 or select_multiple by0xe03) in your survey sheet, but at the same time, by0xe03 is missing under the choices sheet. You could check this out by downloading your survey form as an xlsform and then doing a search by pressing CTRL+F under the survey tab as well as the choices tab. As a backup, you could also check your xlsform here. It should be able to help you point out syntax errors if there are any.
Kindly please note, if you still cannot solve your issue, kindly please feel free to share your xlsform with the community. The community should be able to help you out.
