What causes "Project repository not found for this organization." in mastra-ai/mastra?

Re-select the project repository in the session so projectRepositoryId points to an existing row

Project repository not found for this organization.

Error message

Project repository not found for this organization.

What it means

After resolving session identifiers, resolveSessionTarget loads the project repository record from sourceControlStorage using orgId and projectRepositoryId. If no record exists for that organization, this error is thrown. It indicates the session references a project repository that has been deleted or belongs to another org.

Solutions

Re-select the project repository in the session so projectRepositoryId points to an existing row
Verify the record exists in projectRepositories storage for the session's orgId
Clear/reset the stale session state and re-initialize the repository session

Defensive patterns

Strategy: validation

Validate before calling

const pr = await storage.projectRepositories.get({ orgId, id: projectRepositoryId });
if (!pr) throw new Error('stale projectRepositoryId — reselect the project repository');

Try / catch

try {
  await subscribe(...);
} catch (e) {
  if (e.message.includes('Project repository not found')) {
    // refresh session state: re-select a project repository
  }
}

Prevention

Validate projectRepositoryId against storage when initializing session state
Invalidate sessions when their project repository is deleted
Use onDelete hooks to clear references to removed project repositories

When it happens

Trigger: Session state holds a stale projectRepositoryId while the underlying projectRepositories record was removed, or the id belongs to a different org than the session's orgId.

Common situations: Repository removed by an admin while an old browser session still referenced it; cross-org session replay; data migration dropping projectRepositories rows.
