Image URL to open in Google sheets

All my apps use CONCATENATE(“https://www.appsheet.com/template/gettablefileurl?appName=”, ENCODEURL(“ABC”), “&tableName=”, ENCODEURL(“Appsheet APP”), “&fileName=”, ENCODEURL(“Image Name”)),"")etc to get the url (in Google Sheets )of the image stored in Appsheet that has worked fine till recently. Now all my apps are down because the formula no longer gets the url. Is there some new way to get the url to display the image in Google sheets?
