INVALID_ARGUMENTS

Error message

Cannot register factories after filters are loaded.

What it means

ClientRequestFilterManager.registerClientRequestFilterFactory was called after filters were already loaded; registration is only allowed during plugin setup before the first filter use, so this late registration is rejected.
