Error: [LWC error]: Invalid event type "WireContextEvent" dispatched in element force-aloha-page

Usually when we are rendering any LWC component in Lightning experiences or Lightning console applications sometimes you will receive this error.

The complete looks like below in your browser console

aura_proddebug.js:4283 Error: [LWC error]: Invalid event type "WireContextEvent" dispatched in element <force-aloha-page>. Event name must 1) Start with a lowercase letter 2) Contain only lowercase letters, numbers, and underscores
    at Object.logError (aura_proddebug.js:4279)
    at AlohaPage.dispatchEvent (aura_proddebug.js:7633)

    at AlohaPage.connectedCallback (alohaPage.js:688)
    at callHook (aura_proddebug.js:8345)
logError @ aura_proddebug.js:4283

According to Salesforce LWC Documentation the LWC components are not completely supported in all the environments,applications and display sections.

So,this error comes when your rendering any LWC component in any of the area where salesforce doesn't support these LWC components.


To fix this error please place your LWC component in Aura component then the LWC component will work without any errors.


  • This could also comes in the cases where your using any lightning interface or feature which will not support in classic environment then also this comes.
  • In those cases wrapping inside the aura also will not help us.

Hope this helps you..Enjoy..!
