React component calling issue with props using Redux and connect

I have this code

    return (
        <SideBar {...sideBarProps}>
            <div className='main'>
                <section className='touch-option'>
                    <div className='title'></div>
                    <div className='explain'>
                        <DashboardLead actions={this.props.actions}
                                       dispatch={this.props.dispatch}
                                       leads={this.props.leads}/>
                        
                    </div>
                </section>
            </div>
        </SideBar>

        );

I am getting error un-define method map, that means i am note getting leads array through this.props.leads.

Please help me on this.
