Error while setting up file platform for sensor

Hi,

since 2021.6.2 my sensor to read the log file doesn’t work anymore.

I get:

Error adding entities for domain sensor with platform file
Error while setting up file platform for sensor

    raise InvalidStateError(
homeassistant.exceptions.InvalidStateError: Invalid state encountered for entity ID: sensor.log_tail. State max length is 255 characters.

This is my configuration on the sensor.yaml

 - platform: file
    file_path: /config/home-assistant.log
    name: Log tail
    value_template: >
      {{value|truncate(255,True)}}
