umbraco forms posting from protected page gives ysod

Question

Using Umbraco version 7.4.3 assembly: 1.0.5948.18141 After creating a form using umbraco 7.4.3 the form works as expected, except when we access the form via a protected page. The form displays, and allows user interaction, however we are unable to submit form from protected page.

There was a question posed on the umbraco forum that suggested a fix was found, but no information for that fix was posted here -> https://our.umbraco.org/forum/umbraco-forms/78933-umbraco-forms-and-protected-pages , I have also posted a question regarding this issue in the umbraco forums - no answer todate.

YSOD when submitting form from a protected page. Stack trace below:
