Worked on stabilizing the Strapi v5 migration process by addressing a SQL query ambiguity within the strapi/strapi repository. Focused on database migration scripts, the developer resolved an issue where ambiguous field names in GROUP BY clauses could disrupt migrations involving internationalized content types. By explicitly qualifying the joinColumn table in SQL statements, the fix ensured accurate handling of potentially conflicting field names, reducing upgrade risks and improving data integrity. The work was implemented using SQL and TypeScript, with clear traceability through commit messages and issue linkage. This targeted bug fix enhanced the reliability of Strapi v5 database migrations.
