Grok pattern

Hi. I am trying to parse this log message:

2024-12-09 12:33:53,722 ERROR [Timer-Driven Process Thread-10] o.a.n.processors.standard.LogAttribute LogAttribute[id=9b65f63b-0193-1000-ffff-ffffd5fe4484] logging for flow file StandardFlowFileRecord[uuid=44e26a91-9cd3-4b89-820c-c017b6bb167e,claim=StandardContentClaim [resourceClaim=StandardResourceClaim[id=1733479320437-1, container=default, section=1], offset=67, length=26],offset=0,name=6e40fa80-02b3-4e3a-b0cf-454a8442f7e4,size=26]

b, invokehttp.status.code=404, uri=ul/get}

But cannnot parse FlowFile Properties object - I need to get invokehttp.response.body, invokehttp.status.code and uri fields. Does anybody have any ideas how this can be done? Thank you in advance.
