C++ stack traces aren't being demangled


We’re using an on-prem OSS solution, and I thought I had everything working, but I’ve noticed our C++ backtraces are not being demangled. I have all the binaries/source uploaded, and the source locations are being parsed correctly, but the function names are all mangled still. Is there something obvious I could be missing? My server is “20.12.1bade073” and I’m using the SDK 0.4.1, if that helps. I’m also setting sentry_options_set_symbolize_stacktraces(options, 1).

Thanks in advance, Matt
