X_ERROR_REPORTER_DSN_UNCLAIMED
Means
SENTRY_DSN is set, and the app installed a reporter marked neither as its Sentry transport nor as a local sink
Typical cause
the app installs an ErrorReporter of its own (a wrapper around sentryErrorReporter, a hand-written sink) without sentryTransport() or localErrorSink(), and the container also sets SENTRY_DSN; it might already be a transport, so the boot adds none and the DSN is unused
Fix
edit the file that calls configureErrorReporting: wrap your Sentry wrapper in sentryTransport(wrapper), or a reporter that keeps reports on the box in localErrorSink(sink)
