     />

in fullObject i save the object that i recieve from graph.

Any help would be greatly appreciated.

On componentDidMount I have received the current logged in user using MSGraphClient. I have saved the object that I received from graph in fullObject variable.

I am using below code:

<NormalPeoplePicker
    onChange={this._onChange.bind(this)}
    onResolveSuggestions={this._onFilterChanged}
    getTextFromItem={(persona: IPersonaProps) => persona.primaryText}
    pickerSuggestionsProps={suggestionProps}
    className={'ms-PeoplePicker'}
    key={'normal'}
    itemLimit={1}
    selectedItems={this.state.fullObject}             
/>

How can I set this user as a default in the PeoplePicker field?

Any help would be greatly appreciated.
