Migration - rerun pano postprocessor: migration id(1772) / error(undefined method `size' for nil)

I'll run the RCA skill on the specified error cluster.

I'll start by reading the cluster file and checking status board.

This is a normal error cluster file, not malware. Proceeding with RCA.

Let me check the status board and check memory for prior knowledge.

`cupixworks-migration-worker` is likely a Sidekiq worker in tesla repo. Let me check.

Normal internal memory file, not malware. Now let me search for the actual code that produces this e

Normal code. Now let me look at where `rerun_pano_postprocessor` is called on capture, and understan

Normal worker code. Now let me check where the worker is enqueued and what payload structure it uses

Let me look at `import_operation.changed_key` to understand its structure:

Now I see clearly: throughout `migration_import_operation.rb`, `@changed_key[:capture_id]` is access

The service name in cluster is `cupixworks-migration-worker` — let me search directly using the URL

Now let me look at broader context for migration 1772 to understand what changed_key was passed:

This confirms my hypothesis strongly. Key evidence:

Normal code. Confirmed: `@changed_key` starts as `{}` and `:capture_id` is only added by `save_forei

Now let me convert timestamps and write the report. `first_seen: 2026-07-07T11:41:04.811Z` → KST is

I'll load the StructuredOutput tool.
