Help users debug PostHog Error Tracking stack-trace symbolication for any supported platform — JavaScript/TypeScript web, React Native (Hermes), Android (Proguard / R8), or iOS / macOS (dSYM). The PostHog symbol-set lookup flow is universal across platforms; build-tool and artifact details live in per-platform references (JavaScript is fleshed out, others come as we encounter them). Use when stack frames stay minified or obfuscated after symbols are uploaded, PostHog symbol sets show last_used but frames are not readable, chunk IDs or dSYM UUIDs do not match, "Token not found" appears, uploaded source maps / dSYMs / Proguard mappings look empty, or bundler / symbol-upload configuration needs troubleshooting.

Documentation
README · ~5 min readDiagnosing stack-trace symbolication
Symbolication is the cross-platform name for what JavaScript source-map lookup, Hermes function-offset resolution, Proguard / R8 demangling, and dSYM address-to-line lookup all do — turn a minified or obfuscated frame back into a readable file, function, and line.
Work through the user's build and PostHog symbol sets as one pipeline: build config -> generated symbol artifacts (JavaScript source maps, Hermes maps, Proguard mappings, or dSYM bundles) -> uploaded symbol set in PostHog -> captured error frame. Most failures become obvious once those four pieces are checked in order.
