Component Not Found Error

I have a form that works fine when I enter the URL as
​
https://mysite.com/index.php?option=com_chronoforms6&chronoform=form_name.
​
However, I created a menu item using the Chronoform link and added the form name. When I click on the link, the browser goes to :
https://mysite.com/index.php?Itemid=145
and it loads the form correctly. But when I submit the form, I get Component not found error.
​
On the error page, looking at the URL it is as below:
https://mysite.com/index.php?Itemid=145&chronoform=form_name&event=submit

I think this link and the form were working fine in the past. I'm not sure what caused them to stop working? The submit return URL is wrong.
Any idea on how to fix this?
Thanks

Hi omidhz,
​
Please set the form Action URL to the correct submit URL - you can either type in the whole thing, or you can create a hidden CF menu item and set the event to Submit then use the short menu URL.
​
I don't know why you are getting the ItemID in the URL - you did create a CF Menu item and not an Article one?
