Failed loading content url after saveCatalogNode

Hi Everyone,

I am trying to call saveCatalogNode of ICatalogSystem inside the PublishedContent event but unfortunately, after clicking publish button I always get this error

after several attempts of figuring the cause, i noticed that as soon as after calling saveCatalogNode, the HttpContext.Current.Request.Url was updated to this wrong url. The correct url in our set up is "epi.cms.contentdata:///1073742255_CatalogContent" but after saveCatalogNode, it added 2122933 on the middle part. Any ideas on why it changes the request url? and is there a way to retain the original one even after calling savecatalognode method? Thanks.
