Space is empty in lock software

The error message "You are trying to check out a guest from a door which is already vacant, or you are trying to add a companion guest into an already vacant room." can occur if you have a hostel setting in the Data JSON field for the key encoder configured in your key cutter integration.

 

When you have included the line "DuplicateKeyAllowed": "True" in the Data JSON, Mews always creates a joiner/duplicate card. When there are no valid cards registered in your door lock software linked to the space for which you are trying to create a key, the door lock software throws this error.  
 

 

To prevent the error, follow these steps:

 

1. Check if any of your key encoders configured in the key cutter integration in Mews uses the hostel setting. If yes:  
   1. Delete any previously created key in that space.
   2. Try to create a new key for that space, directly in your door lock software.
   3. Try to create a key from Mews, and observe whether the same error message occurs, see How to find logs from the Mews Connector app. 
2. If your property is not a hostel, you do not need to have the line "DuplicateKeyAllowed": "True" in your key encoder configuration.
3. If your property is a hostel, but you have individual bed spaces configured in your door lock software, and you have mapped these spaces in Mews, then you do not need the line "DuplicateKeyAllowed": "True".
