Apm agent misses some requests

When the developer came to me, I found out that apm didn't log some requests, I don't know why.
I can see the request record in the log, but I can't find any data for this request on the apm UI.




I didn't put any restrictions on apm agent, even if I execute the request repeatedly, the apm agent still doesn't have any records.
