500 Error on Episerver form submit.

Problem:

We are encountering 500 error when submitting Episerver forms occasionally.

The exact 500 error is anti-forgery token is missing.

We have confirmed that the form submission is allowed for anonymous user.

Relative Package version:

Episerver.Contentdeliveryapi.forms  v 2.6.1

Episerver.form V 4.25

Some details to note:

Our content site is powered by react, thus we followed the guide on https://world.episerver.com/documentation/developer-guides/content-delivery-api/content-delivery-api-and-episerver-forms/.

We are able to render the form successfully using data provided by content delivery api and javascript.

After some debugging, I noticed that the content delivery api is returning a set cookie header for __requestVerficationtoken.

Occasionally the value of the cookie is missing, and this is causing 500 error on form submit.

If we get a correct response from content delivery API, we are able to submit the form without any error.

Does anyone ran into this problem before? And is there any workaround on this ?

Hi Wen, Have you used any type caching on the page like [ContentOutputCache] attributes on the page where this form is rendering? If yes then removed the caching from the page and then try because when the page gets reload then the cookie is not refreshing and throwing 500 errors.
