BTicino Smarther API issue

Dear All,
since a while I’m receiving this error:

2022-06-28 14:07:41.641 [WARN ] [ternal.handler.SmartherBridgeHandler] - Bridge[bticinosmarther:bridge:xxx] Cannot retrieve available locations: java.lang.NumberFormatException: null

This will generate an infinite loop that will run out of the daily API calls available trough legrand website.
Any suggestion? Any way to handle this?
