Second example here Open as an inline full page with a record context

Reported:

The code sample for AppStart and parsing the recordId is incorrect. You must use the MID function to strip the value between curly brackets ({GUID})

Current:

App.OnStart=Set(RecordItem, 
    If(IsBlank(Param("recordId")),
        First(<entity>),
        LookUp(<entity>, <entityIdField> = GUID(Param("recordId"))))
    )

Proposed:

App.OnStart=Set(RecordItem, 
    If(IsBlank(Param("recordId")),
        First(<entity>),
        LookUp(<entity>, <entityIdField> = GUID(Mid(Param("recordId"), 2, 36))))
    )
