Embedded form errror 403

Hi
I embedded a form that requires using a Kobo account to be submitted. When I filled in my username and password to log in, the result was an error: invalid csrf token Error Code: 403
But if I use the form link directly, without using the embedded form, there is no error.
Is embedding a form and requesting a Kobo account incompatible, or is there a solution?

Thanks
Pablo

@pschweitzer, could you kindly share with us a screenshot of your issue so that we can understand your issue pictorially?

Hi @Kal_Lam
This is the embedded form

But when I fill with my username and password, return this error

The goal is to use an embedded form, and have that form require a username and password to be filled in.
Thanks
