I upgraded my project from 10.4 to 11 today and I am getting the below error. It seems to be getting stuck on AppPreBootstrap.ts file in the method getApplicationConfig. It gets to line 83 and errors out on getting the custom headers below. Any idea what could be causing this? My project has multiTenancy off. It is a single tenant project.

let customHeaders = [ { name: abp.multiTenancy.tenantIdCookieName, value: abp.multiTenancy.getTenantIdCookie() + '', },
