I am trying to make a post request from my admin settings page for a new plugin.
The following code takes me to a blank page after submit (URL is: http://192.168.1.33:3000/wptest2/wp-admin/admin-post.php).
No var dump, no redirect to google. No console errors and I don't see any apache errors in the log either. I suspect the form is not submiting to the correct destination.
<form
action="<?php echo
esc_url(admin_url('admin-post.php'));
?>"
method="post"
id="newCouponForm"
enctype="multipart/form-data"
>
<input
type="hidden"
name="action"
value="handleNewCoupon"
>
<button type="submit">Create New Coupon</button>
</form>
// other form fields removed
// in my main plugin file
function setupCouponTargetImageUpload() {
?>
<script>
console.log(`=====test=====`); // doesn't log
</script>
<?php
$couponType = selectCouponType();
var_dump($couponType);
echo '=====$couponType====='; // doesn't echo
if($couponType === 'image') {
insertImageCoupon();
} else if ($couponType === 'text') {
insertTextCoupon();
}
wp_redirect(''); // no redirect
exit; // removing this has no effect either
}
add_action('admin_post_handleNewCoupon', 'setupCouponTargetImageUpload');
Here is the request to admin-post in Chrome's Network tab. Can anyone spot the issue with this request?

Reset to default 1(Revised answer)
I have changed my action to yours but it still doesn't work. Here is my repo for this plugin if you want to see. I'm at a loss at the moment: github/SeanDez/frequentVisitorCoupons
So I tried and tested your plugin, and noticed that you've got two "actions" (i.e. action fields) on the same form.
<input type="hidden" name="action" value="handleNewCoupon" /><input type="hidden" name="action" value="fromNewCouponForm">
So by now, I bet you know what happened?
I.e. The posted action is fromNewCouponForm instead of the handleNewCoupon (which is the correct one?). And since there's no action hooked to admin_post_fromNewCouponForm, then you got the blank (wp-admin/admin-post.php) page.
