If you receive the Error while invoking AddModifierToTransaction error on the Online Ordering POS Integration app for Aldelo - there is a communication issue between your Aldelo POS server & Orders2me account
You'll need to verify that all items & modifiers are mapped on the Orders2me back-end. You can access this under Settings > POS Settings. You'll want to go through and map all the options that don't have corresponding POS items attached.
Once that's completed, Follow these steps;
- Shut down the Online Ordering POS Integration App by clicking Exit on App
- Shut down your Aldelo POS (this only needs to be done on the station we're installed on)
- Restart both by double clicking the Aldelo POS Integration app on your desktop (this will launch Aldelo as well)
This will establish a new connection & online orders will flow through as normal
**If Aldelo doesn't launch - please check the status of your Aldelo API License
