从Promise正确传入Apex方法参数？

Question

如果我给它一个参数，我会不断从我的承诺的响应中收到错误。我不知道是否应该将“columndefinitions”参数传递给 apex 方法。我附上了图片以提供帮助。 PS：如果我省略参数，它会返回一个空数组，但不会出现错误。

想法：我是否错误地传递了参数？我的列定义格式是否错误？是语法问题吗？

JS 文件

//before render, call an apex method query...
connectedCallback() {
   getValidFields(this.getColumnDefinitions)
             .then((response) => {
                console.log('getvalidfields', response)
               }).catch((error) => {
                console.error(error);
});

getColumnDefinitions() {
        return [
            {
                object: "Contact", apiName: "Name", label: 'Name', fieldName: 'contactURL', type: 'url', iconName: 'standard:contact', sortable: 'true',
                filterable: true, typeAttributes: { label: { fieldName: 'contactName' }, target: '_self', tooltip: 'Click to view Contact details' }
            },

        ];
    }

如果从 LWC 命令式调用 apex 操作，则应该将参数作为对象传递。对象属性的名称应类似于您的 Apex 方法参数。

在你的情况下应该是：

getValidFields({ columnDefinitions: this.getColumnDefinitions()} ).then(...)
