E_NOTICE's when using a saved export mapping
I'm still checking the minimal settings to trigger it and when it started, but regardless looking at the code it seems obvious the variable names are not defined. But it seems you need to choose a certain set of fields, e.g. firstname, lastname, phone doesn't seem enough.
Notice: Undefined variable: phoneType in CRM_Core_BAO_Mapping::loadSavedMapping() (line 1045 of /srv/buildkit/build/dmaster/web/sites/all/modules/civicrm/CRM/Core/BAO/Mapping.php).
Notice: Undefined variable: phoneType in CRM_Core_BAO_Mapping::loadSavedMapping() (line 1054 of /srv/buildkit/build/dmaster/web/sites/all/modules/civicrm/CRM/Core/BAO/Mapping.php).
Notice: Undefined variable: imProvider in CRM_Core_BAO_Mapping::loadSavedMapping() (line 1054 of /srv/buildkit/build/dmaster/web/sites/all/modules/civicrm/CRM/Core/BAO/Mapping.php).
Will update with more info.
