SEO report & "search queries vs search results" return 500 ("Cannot read properties of undefined (reading 'map')")

Two MCP tools have been returning a 500 error for us since 17 June 2026, still failing
as of 23 June (re-tested today):

- search_queries_vs_search_results
- generate_seo_report (SEO report)

Error in both cases:
500 — { "error": "An error occurred while processing the request",
        "message": "Cannot read properties of undefined (reading 'map')" }

Isolating the pipeline (same account, same query, all tested today):
- analyze_google_search_results — works
- analyze_related_search_queries — works
- search_queries_vs_search_results — 500s when combining them (also with
  includeSearchQueriesOnly:true)

So both inputs to the comparison succeed and only the comparison step crashes. It looks
like an unguarded .map() on an undefined value in that step. generate_seo_report (which
builds everything fresh from a URL) fails with the identical error, so it isn't a missing
saved graph on our side.

Repro (via the MCP connector):
- search_queries_vs_search_results with queries: ["ecommerce personalization platform"]
- generate_seo_report with url: https://www.helloretail.com/en/

It reproduces on a single generic query that definitely has SERP results, so it doesn't
seem query-specific. Other tools (graph generation, content gaps, text analysis) and auth
all work fine on the same account.

I emailed Dmitry on 17 June with follow-ups on 18 and 22 June but haven't heard back, and
couldn't get through the Discord human-verification step, so flagging here too. Happy to
share the account email and a full reproduction privately. Thanks!
