Hello Everyone,
I've a lightning out app, and added this app in salesforce "Sites".
I'm not receiving any emails as I'm supposed to receive based on some action in the lwc app placed in lightning app. 
I've given the apex class permission to Guest site user. In debug log I checked the status of email is success = true.. still I'm not able to receive emails.
Can anyone know what extra pernission should we give in order to receive emails from Guest site user?

Hello Experts,

I dont find any standard documentation on importing custom object and its field to import in lwc js.

Like how do we even import custom obect's picklist and show them on frontend? 

Can anyone help me with this?

Hello All,

Can I get the solution for the error: 

EXCEPTION_THROWN [11]|System.CalloutException: The URI is invalid.
This error is thrown when the endpoint URL has special characters like in query there is * and > symbol so it is not acceptable as proper endpoint URL.
Below is the code for the endpoint URL 
In one of the  POST (https://trailblazer.salesforce.com/issues_view?id=a1p4V000001JkjTQAS), it says special characters in URI are not working after Spring 21.
 

String query='select * from Invoice where Metadata%2ECreateTime > \'2021-06-01T03:58:32.968-07:00\'';
req.setEndpoint('callout:SalesforceQB_Production'+'/v3/company/xxxxxxxxxx/query?query='+query+'&minorversion=59');

Any integration experts here?
