What to do now

Most likely: The credential is valid but lacks access to the requested model, organization or policy scope.

  1. Confirm model availability and organization membership for the active account.
  2. Check enterprise policy or gateway allow-lists before rotating credentials.
  3. Capture the permission error body when asking an administrator for access.

These are conservative triage steps, not an official Anthropic fix. Use the issue and workaround evidence below before making a destructive configuration change.

Which builds report this

115 of these reports name the Claude Code build they were running, spanning 70 releases. Heaviest reporters:

Report volume, not a defect count: an issue can mention a build without that build having caused the failure. Versions come from the version string in the bug-report template, matched against real published tags.

Do these get fixed?

Median time to close is 28 days across 224 closures. Of the 224 closures with a recorded reason, 27% were closed as completed and 163 as not-planned or duplicate. The most recent completed fix landed in 2026-10.
