设置用户部门失败: %w

Error message

设置用户部门失败: %w

What it means

Wrap of an upstream HTTP error from POST /user/setUserDepartments when updating a member's departments. The assigner's own logic succeeded; the actual write against the admin backend API failed and the underlying error is chained via %w.

Solutions

1. Read the wrapped cause (%w) to see the upstream status/message and fix accordingly
2. Confirm the admin backend API is reachable and healthy from the MCP server
3. Check the MCP credentials have rights to call /user/setUserDepartments for this tenant
4. Retry after confirming the target user and dept IDs still exist

if user == nil || len(deptIDs) == 0 && primaryDeptId == 0 {
    return errors.New("nothing to assign: provide deptIds or primaryDeptId")
}

res, err := assigner.Handle(ctx, args)
if err != nil {
    var upstreamErr *url.Error
    if errors.As(err, &upstreamErr) {
        // network-level failure: check backend health, retry with backoff
    } else {
        // upstream returned an error status: inspect message for status/body
    }
    return fmt.Errorf("set departments failed: %w", err)
}

When it happens

Trigger: Handle calls postUpstream to /user/setUserDepartments and the upstream returns a non-2xx status, auth failure, validation rejection (e.g. invalid deptIds/primaryDeptId combination), or the server is unreachable.

Common situations: Backend service down or restarted; MCP token lacks casbin permission for the user API; concurrent modification where the user was deleted mid-flow; department IDs referencing soft-deleted depts.
