Salesforce -使用消息服务问题发布Aura组件

Question

我正在尝试将Aura中的数据发布到LWC。我得到了错误，以纠正我遗漏的东西。我检查了多个例子作为语法智慧，仍然不起作用。因此发帖看看是否有人能帮上忙。

Aura组件html：

<aura:component implements="flexipage:availableForAllPageTypes,flexipage:availableForRecordHome,force:hasRecordId" access="global" >
   <a href="javascript:void(0);" onclick="{!c.publishMC}">More Information</a>
   <lightning:messageChannel type="AlertMessageChannel__c" aura:id="AlertMessageChannel"></lightning:messageChannel>
</aura:component>

Aura控制器JS：

({
publishMC : function(component, event, helper) {
    var messageInfo = [
        { normalTxt: '', boldTxt: '', boldLeftTxt: 'This opportunity is Stale', 
        normalRightTxt: 'the stale reason code is EOD PAST DUE.'},
        { normalTxt: '', boldTxt: '', boldLeftTxt: 'This account has 1 or more Frame 
         Agreements', normalRightTxt: 'There is a Frame Agreement associated to the account, 
         if applicable, please link to this opportunity using the Contract ID field.'},
    ];
    component.find("AlertMessageChannel").publish(messageInfo);
    }
})

我还添加了消息服务xml文件

<?xml version="1.0" encoding="UTF-8"?>
<LightningMessageChannel xmlns="http://soap.sforce.com/2006/04/metadata">
<description>This is a alert message channel communicator</description>
<isExposed>true</isExposed>
<lightningMessageFields>
    <description>Header information passed into alert modal window</description>
    <fieldName>alertHeaderInfo</fieldName>
</lightningMessageFields>
<lightningMessageFields>
    <description>Body information passed into alert modal window</description>
    <fieldName>alertBodyInfo</fieldName>
</lightningMessageFields>
<lightningMessageFields>
    <description>Show/Hide information passed into alert modal window</description>
    <fieldName>alertVisibleInfo</fieldName>
</lightningMessageFields>
<masterLabel>AlertMessageChannel</masterLabel>

但是当尝试加载时，得到的错误如下：

操作失败: Lightning : MessageChannel $MessageChannel$init Lightning Message Service -无法识别的控制器引用: AlertMessageChannel__c

有谁能帮助我，我错过了什么？

Answer 1

该消息似乎表明您的消息通道未被识别。"masterLabel“不是消息通道的接口名称，而是文件名。例如，如果你在一个文件AlertMessageChannel.messagecannnel-meta.xml中定义了你的xml，那么你可以用"AlertMessageChannel__c“引用你的频道。如果你的文件名不同，比如"TestChannel.messageChannel-meta.xml“，那么你必须使用"TestChannel__c”。
