Description

parity

[!WARNING]
Auto-generated parity issue — may be a false positive.

This issue was created automatically by /sync-sdk-parity from a heuristic analysis of recent supabase-js commits. The tooling has limited insight into language-specific idioms and may have:

  • misidentified a JS-only change as cross-language relevant,
  • missed an existing implementation in this SDK under a different name,
  • or proposed an API shape that doesn't fit this language's conventions.

It is the SDK author's responsibility to validate the need before implementing. If this change does not apply to this SDK, please close the issue with a short note explaining why.

SDK Parity: C# implementation needed

A defensive fix was made in supabase-js auth that may apply to this repository. Please confirm applicability before starting work.

Reference Implementation (supabase-js)

  • Commit: 0c227a1
  • PR: supabase/supabase-js#2336
  • Module: auth
  • Type: bug-fix (resilience)
What Changed

Session-storage reader returns null on JSON parse failure, treating corrupted entries as absent rather than crashing downstream.

Implementation Guidance (C#)

private Session? ReadSessionFromStorage()
{
    var raw = _storage.GetItem(_storageKey);
    if (raw == null) return null;
    try
    {
        return JsonSerializer.Deserialize<Session>(raw);
    }
    catch (JsonException)
    {
        return null; // Corrupted — treat as no session
    }
}
Key Behaviors to Match
  • Invalid JSON in session storage → null, not exception

Acceptance Criteria

  • Corrupted session storage returns null, not throws
  • Test verifies the behavior

Context

  • supabase-js version: v2.106.0
  • Related: SDK-1038 (dart), SDK-1039 (py), SDK-1040 (swift)
  • Parity tracking: Auto-generated by /sync-sdk-parity
