Logic Apps - Tracked properties for HTTP action`s INPUTS not working

Can someone help me and tell me why tracked properties for HTTP action`s INPUTS not working
I get an error:
TrackedPropertiesEvaluationFailed

Failed to evaluate the tracked properties for action 'HTTP_2'. Error details: 'The template function 'inputs' is not defined or not valid.'.
In case for OUTPUTS everything works

My tracked properties are
@{outputs('HTTP_2')?['statusCode']}
@{inputs('HTTP_2')?['uri']}
