ERROR: Service_Agent_Exception

[fandar]

Hello,
after upgrade I cannot open plesk panel and I am getting this error

ERROR: Service_Agent_Exception
Eine Ebene höher
Unable to execute php_handlers_control: Error reading /etc/psa/php_versions.json: can not parse php_versions_info object : JSON object is expected. Error occured at offset 0, character '\x00'.

I have found that the file /etc/psa/php_versions.json is empty

Could anybody please attach here how the php_versions.json file should look like?
Thank You in advance
