How to resolve the error - Cannot find Lightning Component
am trying to follow this trailhead module and I am trying to create a selector lightning web component with code
import { LightningElement, track, wire } from 'lwc';
import { getRecord, getFieldValue } from 'lightning/uiRecordApi';
import Id from '@salesforce/user/Id';
import NAME_FIELD from '@salesforce/schema/User.Name';
const fields = [NAME_FIELD];
export default class Selector extends LightningElement {
@track selectedProductId;
handleProductSelected(evt) {
this.selectedProductId = evt.detail;
}
userId = Id;
@wire(getRecord, { recordId: '$userId', fields })
user;
get name() {
return getFieldValue(this.user.data, NAME_FIELD);
}
}
but it fails with error Cannot find Lightning Component Bundle selector.

Cannot find Lightning Component Bundle selector.Answer (1)
The error "Cannot Find Lightning Component" typically occurs in Salesforce when there is an issue with the Lightning Component or the way it is being referenced. Here are several steps to resolve this error:
1. Check Component Availability
Namespace Prefix: Ensure that the namespace prefix is correctly included if you are working within a managed package.
Component Name: Verify that the component name is correctly spelled and matches the one defined in the .cmp or .js file.
Component Location: Ensure that the component is deployed and exists in the correct directory in your Salesforce org.
2. Verify Component Registration
Include in App or Page: Make sure that the component is included in the appropriate Lightning App, Lightning Page, or Aura App.
My Domain: Ensure that "My Domain" is deployed and that you are accessing the correct URL, especially if the component is part of a managed package.
3. Component Accessibility
API Version: Check the API version of your component. Some features are only available in certain API versions.
Access Control: Verify the component’s visibility settings. Ensure it is marked as global if it needs to be accessed across different namespaces.
4. Static Resource Issues
Static Resource Deployment: If your component relies on static resources, ensure those resources are correctly uploaded and accessible.
Resource Paths: Verify that the paths to static resources are correct.
5. Clear Cache and Refresh
Clear Browser Cache: Sometimes, clearing the browser cache can resolve issues related to stale data.
Hard Refresh: Perform a hard refresh of the page (Ctrl + F5 on Windows or Cmd + Shift + R on Mac).
6. Check Dependencies and References
Dependencies: Ensure all dependencies (like other components or libraries) are correctly referenced and available.
Reference Paths: Verify that the paths used in aura:dependency or import statements are correct.
7. Inspect the Developer Console
Debug Logs: Use the Salesforce Developer Console to check debug logs for any errors or warnings that might give more insight.
Console Errors: Look for JavaScript console errors in the browser’s developer tools.
8. Lightning Web Components (LWC) Specific Checks
Import Statements: Verify that the import statements in your LWC JavaScript files are correct.
LWC Registration: Ensure the LWC is correctly registered in the metadata (.js-meta.xml file).
Deploy Components: Make sure that all necessary components are deployed to the Salesforce org.
Example Checklist for a Lightning Component
Here’s a checklist to help you systematically troubleshoot the issue:
Namespace and Naming:
Verify namespace prefix and component name.
Check for typos or mismatches in the component name.
Deployment Status:
Ensure the component is deployed.
Verify the component is in the correct Salesforce org and environment.
Component Reference:
Ensure correct referencing in other components or Visualforce pages.
Check the aura:dependency and import statements.
Visibility and Access Control:
Confirm the component’s access level (global if necessary).
Check sharing and visibility settings.
Static Resources:
Verify static resources are uploaded and accessible.
Check paths to static resources.
Cache and Refresh:
Clear browser cache and perform a hard refresh.
Try accessing from a different browser or incognito mode.
Error Logs and Debugging:
Check Salesforce Developer Console for errors.
Inspect browser console logs for JavaScript errors.
Dependencies and Metadata:
Ensure all dependencies are correctly included.
Verify metadata files (like .js-meta.xml for LWCs).
Example LWC Registration (.js-meta.xml)
56.0
