Retained heap is 0 for all threads?
trafficstars
I captured a snapshot of large production backend app running under uvicorn (in a cloud container) and am trying to analyze it on my own machine. Both the web ui and the cli analyzer show 0 retained heap for every thread:

Additionally, when I click on the "heap" tab in the web ui; nothing happens.
Any idea what might be wrong? I'm running the version from the current main branch.
