I can't deploy my project it's says error 500

@fishoanfrancis, it is a form design issue as outlined by @nat. You should be able to learn more about the same through this post discussed previously:

Choice duplicate

Hi @maggib, I found the duplicate that i have highlighted with yellow and marked the font with red within list_name lf3sx85 whose name prefer_not_to_answer is seen repeated twice within list_name lf3sx85. For your ease check row number 89 and 93 under choices tab. [Image 1] The principle behind this is that each list_name should have unique code under it’s associated name. e.g. this is not allowed … list_name name test a test a test a … but this is allowed … list_name na…

All you need to do is go to your choice sheet and then check row 108 to check for duplicates in your choices sheet.

BTW, feel free to validate your XLSForm through this online validator to see if there are any syntax issues in your form that are affecting the deployment.
