After integrating phone number verification into a Flutter app, I faced the situation of “the verification code isn’t arriving.” And when pressing the dev bypass button to skip verification and attempt signup, the server returned “Phone number verification not completed.” Documenting both issues together.

Notes on integrating the DART Open API (Korea’s Financial Supervisory Service disclosure system) with a Rails backend. Implemented 5 areas: disclosure monitoring, audit opinions, governance, financial indexes, and equity reports – each step came with its own struggles. Implementation Structure Created a model and ActiveJob for each data type. Each job calls the DART API and inserts data using upsert_all – simple structure. DartCorpCodeSyncJob -> dart_companies (company master) DartDisclosureSyncJob -> dart_disclosures (disclosure list) DartMajorEventSyncJob -> dart_major_events (delisting trigger events -- DS001) DartAuditOpinionSyncJob -> dart_audit_opinions (audit opinions -- DS002/DS003) DartGovernanceSyncJob -> dart_executives / dart_major_shareholders (DS004/DS005) DartFinancialIndexSyncJob -> dart_financial_indexes (fnlttSinglAcntAll) DartEquityReportSyncJob -> dart_equity_reports (equity disclosures) Struggle 1: upsert_all + update_only + updated_at Duplication The first error to hit. ...
