Logs

Template warning: 'timestamp_custom' got invalid input '00:00' when compiling template '{{ '00:00' | timestamp_custom('%H:%M') }}' but no default was specified. Currently 'timestamp_custom' will return '00:00', however this template will fail to render in Home Assistant core 2021.12

Screenshots n/a

Additional context Lines 85-92 in keymaster_common_child.yaml:

            - service: input_datetime.set_datetime
              data_template:
                entity_id: "input_datetime.{{ days[repeat.index - 1] }}_start_date_LOCKNAME_{{ code_slot | string }}"
                time: "{{ '00:00' | timestamp_custom('%H:%M') }}"
            - service: input_datetime.set_datetime
              data_template:
                entity_id: "input_datetime.{{ days[repeat.index - 1] }}_end_date_LOCKNAME_{{ code_slot | string }}"
                time: "{{ '00:00' | timestamp_custom('%H:%M') }}"

Likely similar in keymaster_common.yaml
