Start with the GET /api/analyzer/URLhaus_2_0 request and inspect WorkerSrv.scala around line 83. Reproduce the analyzer configuration and compare the configured worker UID with the worker Cortex can find; done means the configured analyzer no longer produces the reported 404, or the missing-worker cause is clearly documented.
