When running machine versions below 0.5.14, a bug in the dispenser logic will result in the machine going to 'Out of cash' when attempting to dispense more than 20 notes of a single denomination.
This is shown in the transaction logs with the entry '23' (0x17) in the error column.
We have corrected this with machine version 0.5.14 and up. Please contact us at email@example.com to arrange an update.
Subsequent server update
If your machine had been on a version below 0.5.5, following the update the machine will go to one-way (cash-in) mode, until the server version is subsequently updated.
After we have confirmed that your machine was successfully updated, run the following command on your server:
npm -g install lamassu-server
The machine will then re-enter two-way mode.
