## I have read the [CONTRIBUTING.md](https://github.com/supabase/supabase/blob/master/CONTRIBUTING.md) file. YES ## What kind of change does this PR introduce? Bug fix. ## What is the current behavior? Closes #46829. When a cron job's command uses `jsonb_build_object(...)` header syntax, `parseCronJobCommand` captures the argument list with `([^)]*)` (stopping at the first `)`) and splits it on every `,`. A header name or value that legitimately contains a comma or parenthesis is split into the wrong pairs, shifting every following header and leaving a trailing header with an undefined value. Because the edit sheet rebuilds the command from these parsed fields, saving a job (even just changing its schedule) silently rewrites its stored headers. ## What is the new behavior? The `jsonb_build_object` argument list is parsed with a scanner that respects single-quoted SQL literals (`''` escapes) and nested parentheses, splitting only on top-level commas. Header names and values containing commas or parentheses now round-trip unchanged. Added four regression tests in `CronJobs.utils.test.ts`. ## Additional context Verified locally: `vitest` cron suite 48/48 pass (the 4 new tests fail without the fix), `tsc --noEmit` clean, ESLint clean, Prettier clean, and `next build` succeeds. 🤖 Generated with [Claude Code](https://claude.com/claude-code) <!-- This is an auto-generated comment: release notes by coderabbit.ai --> ## Summary by CodeRabbit * **Bug Fixes** * Corrected HTTP header parsing in cron jobs so header values with commas, parentheses, escaped quotes, or escape-string prefixes are preserved and don't corrupt adjacent arguments. * Ensured commas inside header values no longer swallow following body arguments. * **New Features** * Added robust SQL-literal and JSONB-argument parsing to reliably extract name/value pairs from JSONB-style headers. * **Tests** * Added tests covering complex header value cases and whitespace/escaping edge cases. <!-- end of auto-generated comment: release notes by coderabbit.ai --> --------- Co-authored-by: Claude Fable 5 <noreply@anthropic.com> Co-authored-by: Ivan Vasilov <vasilov.ivan@gmail.com>
