Update your ABP version to v4.0.1 or above.

It is due to ContainsKey getting called with null if cookie authentication is not used.

The bug occurred in AbpAutoValidateAntiforgeryTokenAuthorizationFilter and AbpValidateAntiforgeryTokenAuthorizationFilter.

The relevant pull request: https://github.com/aspnetboilerplate/aspnetboilerplate/pull/3986
