Error "Requested attachment does not exist" on Service PortalIssue A catalog item allows the users to download file from sys_attachment table. The file gets downloaded, but immediately after hitting "Checkout/Submit" button a screen appears with the message "Requested attachment does not exist". The new request gets created on the platform, but it gives the above error on service portal.ReleaseAll.CauseOn clicking the download file link, the url changes and points to sys_attachment table instead of the sc_request table to complete the ongoing request creation. The url tries to search the newly created request in sys_attachment table instead of request table and gives the error. This behavior is seen because the download link opens in the same browser tab and changes the current url to point to attachment table instead of the request table. ResolutionOpen Tiny HTML Editor and edit the download file link URL adding the attribute target="_blank" in the <href> tag. This results in the file getting downloaded in a new tab and immediate return to the main tab allowing the request to be completed.
