I can see a couple of problems with this:

1. The buffer sizes are too big. The total buffer size (in bytes) should be less than 32-bit. On android 14, perfetto will emit a better error message, but on android 13, if the total buffer size is too big, you might get a smaller buffer than you expect. You do not need a buffer this big. I would start with a config generated by ./tools/java_heap_dump and ./tools/heap_profile.
2. Do you have permissions to profile "com.xiaomi.mi_connect_service:idm"?. On a userdebug build, you should. On a user build, you can get profiling data only from profileable and debuggable apps. (See https://perfetto.dev/docs/data-sources/native-heap-profiler#heapprofd-targets).

Let me know if you have other questions.
