Hi folks,

I followed this documentation to integrate our DXP-hosted CMS website into Content Marketing Platform. However when I select an existing page from the CMS channel, this error shows up:

Not sure what's wrong with my integration settings, but the CMS Content Tree actually loaded successfully when I hit "Add Content" button. It just broke after I chose a page and selected "Add To Task".

This is my current CMP configuration (I did also add UseCmsCmpPublishingPreviewLinks under Startup as well):

        services.AddCmsCmpPublishing();

        // Allow the quick editor to be embedded into CMP via an iframe
        services.Configure<CookieAuthenticationOptions>(OptimizelyIdentityDefaults.CookieSchemeName, options =>
        {
            options.Cookie.SameSite = SameSiteMode.None;
            options.Cookie.SecurePolicy = CookieSecurePolicy.Always;
        });
        if (webHostingEnvironment.IsDevelopment())
        {
            // This automatically configures dev signing credentials to call Integration API
            services.Configure<CmsServiceOptions>(o =>
            {
                o.AddDevelopmentSigningCredentials();
            });
        }

Have anybody experienced this issue before?

Thank you,
Tung
