OpenCode provider reaches cookie-authenticated session, but fetch fails with HTTP 500

[jeshbarlow]

Environment:

• CodexBar 0.20
• macOS 15.x
• OpenCode provider
• Cookie source: Manual

What I verified:

• I am logged into opencode.ai in the browser
• I can see authenticated POST requests to https://opencode.ai/_server in DevTools
• Request headers include a valid Cookie header
• CodexBar no longer fails with “No OpenCode session cookies found in browsers”
• After supplying the cookie manually, CodexBar fails with:
  “OpenCode API error: HTTP 500: HTTPError”

What I tried:

• Manual cookie from authenticated /_server request
• Workspace override set to:
  wrk_01KNJZ12TYPERCDX6W75FZF8ZZ

Expected:

• CodexBar should fetch workspace/subscription usage from OpenCode

Actual:

• CodexBar returns HTTP 500 from the OpenCode provider
