Error: Maximum update depth exceeded. This can happen when a component repeatedly calls setState inside componentWillUpdate or componentDidUpdate. React limits the number of nested updates to prevent infinite loops.

import React, { Component } from 'react';
import styled from 'styled-components';

class Item extends React.Component {
    constructor(props) {
        super(props);     
        this.toggle= this.toggle.bind(this);
        this.state = {
            details: false
        } 
    }  
    toggle(){
        const currentState = this.state.details;
        this.setState({ details: !currentState }); 
    }

    render() {
        return (
            <tr className="Item"> 
                <td>{this.props.config.server}</td>      
                <td>{this.props.config.verbose}</td> 
                <td>{this.props.config.type}</td>
                <td className={this.state.details ? "visible" : "hidden"}>PLACEHOLDER MORE INFO</td>
                {<td><span onClick={this.toggle()}>Details</span></td>}
            </tr>
    )}
}

export default Item;

when handle event,change this.toggle() to this.toggle or {()=> this.toggle()}
