CONFIGURATION_INVALID

Error message

loadClientRequestFilters can only be called once.

What it means

Lifecycle guard in ClientRequestFilterManager: loadClientRequestFilters had already run (the loaded AtomicBoolean is set), and a second invocation was attempted. Filter factories can only be registered before loading, so this is a duplicate-initialization programming error, not a runtime data problem.

Solutions

1. Call filter loading once during server startup; report repeated invocation as a bug
