[beats receivers] EDOT diagnostics are not collected when diagnostics are requested through Fleet

[cmacknz]

When using the request diagnostics action in Fleet, the edot/ diagnostics sub-directory is missing from the diagnostics. They are present when collected using elastic-agent diagnostics locally.

We are likely missing something in the diagnostics action handler to trigger them.

elastic-agent/internal/pkg/agent/application/actions/handlers/handler_action_diagnostics.go

Lines 90 to 100 in 18beeba

	// The handler has a rate limiter to limit the number of diagnostics actions that are run at once.
	func (h *Diagnostics) Handle(ctx context.Context, a fleetapi.Action, ack acker.Acker) error {
	h.log.Debugf("handlerDiagnostics: action '%+v' received", a)
	action, ok := a.(*fleetapi.ActionDiagnostics)
	if !ok {
	return fmt.Errorf("invalid type, expected ActionDiagnostics and received %T", a)
	}
	go h.collectDiag(ctx, action, ack)
	return nil
	}
