Question

当我调试（xdebug）一些php代码并启动phpmyadmin时，然后登录后， myphpadmin引发以下异常：'PhpMyAdmin \ SqlParser \ Exceptions \ LoaderException：指定的上下文（“ \ PhpMyAdmin \ SqlParser \ Contexts \ ContextMySql50727”）不存在。'

多次按F5键（运行），我似乎登录正确。后来再次发生相同的异常，几个F5以后都没事。

当调试器不活动时，我完全没有问题。

return {

        initialize: async function() {
                console.log(`***** Starting Scheduler on ${dateformat(new Date(), "dd-mm-YYYY h:MM:ss")}`);
                var j = schedule.scheduleJob('*/1 * * * *', function(){
                console.time('Scheduler execution time');
                if(interations === 0){
                    console.log(`Setting scheduler runtime to full time.`);
                }
                interations++;
                // call the method
                this.execute();
                console.log(`Job executed ${interations} times.`);
                console.timeEnd('Scheduler execution time');
            });

        },

        execute: async function {
            var options = {
                url: 'http://example.com',
                method: 'GET'
            }      
            return new Promise(function (resolve, reject) {
                request(options, function (error, res, body) {
                    if (!error && res.statusCode == 200) {
                        console.log
                        resolve(JSON.parse(body));
                    } else {
                        reject(error);
                    }
                });
            });    
        }
    }

异常在源文件的第467行发生： /usr/share/phpmyadmin/vendor/phpmyadmin/sql-parser/src/Context.php：
