Further information
2. To maintain backwards compatibility, attachment operations will only raise exceptions on error if the
raise_attach_exceptions attribute of either the
AppConfig or
AppInterface class is set to
True. When this is not the case, after every call to this method you should check the value of
insight.attach_status to see if your request succeeded.
3. Attempting to access attachments outside an Xpress Insight scenario will access local files that have been supplied to this class.
