# We couldn't find a Lightning web component named 'helloWorld'. 

+ [I have completed the challenge but while verifying the challenge i am getting the error in Create a Hello World Lightning Web Component](https://trailhead.salesforce.com/trailblazer-community/feed/0D54V00007UtFVP)

:::note
I don't think any thing wrong in Component.

Suppose if XML is not proper (Say target missing ) then we will not get option to drag the component on Home page.

Unfortunitly, In this case I would also suggest please go with new Org now.

No worries it will a revison of those deployment commands :) (I usually did multiple times).

Simply Authorise again with SFDX:Authorise an org and login with new playground org.

As I can see all things are good in perfect manner.
but, sometimes this error occurs for following reasons
1) when we have same name components
2) spelling mistake and url issue
open setup --> search in quick find box for 'Lightning components'
Check your 'helloWorld' named LWC component and try to delete it.

If its giving error then remove that component from that page where you set it.(edit page)
now, again re-auth an org and try to deploy that component and set it where you want.
