Why can’t I redirect to delete route in expressjs and js? [closed]

I am trying to make an admin panel for my restaurant website. The system generates a user snippet(admin_panel_user_display_snippet) for every user on the database and replaces the values with their places. I also added a form to delete the user from the database.

The form’s action gets replaced with the /delete-user-John"(let's say the user's name is John). When you get routed to the form’s action; the system deletes the user. But there is a mistake.

I cannot get redirected to /delete-user-John. I get an error called

Cannot POST to /delete-user-john

What am I doing wrong?

var user_card_name_result;
var data_food_snippet_display_replaced = data.replace("#admin-panel-display-user-div-2{display: none;}", "#admin-panel-display-user-div-2{display: flex;}");
