I wanna get fields from a record page. So tried to use metadata query in apex, but it did not look working well.

Below is the code that I tried. What should I write in the code to get fields metadata in apex?

try{
    List<Metadata.Metadata> components = Metadata.Operations.retrieve(
        Metadata.MetadataType.Layout,
        new List<String>{'Account-Account Layout'}
    );
    layout = (Metadata.Layout)components.get(0);
}catch(Exception e){
    System.debug(e.getMessage());
}

In the e.getMessage, the debug List index out of bounds: 0 was shown.

Or should I use xml code?

Thank you in advance.

    To cover the obvious, have you double-checked that that layout name exists? Is the layout you're trying to receive part of a managed package? – David Reed Jul 7 at 14:02
  • Yes, might be layout name issue. This code is working fine and getting layout information. – Dhanik Lal Sahni Jul 7 at 14:06
  • @DavidReed Could you tell me how can I know the layout name? Should I add some additional code to get layout name? or is it possible to check layout name from Salesforce setting? – Shin Jul 7 at 14:13

This code appears to be correct, so I believe the problem is simply that your org does not contain a Page Layout called "Account-Account Layout".

If you navigate to the Account sObject in Setup->Object Manager, and click Layouts, you'll see a list of layout names:

Layout list

The metadata component name for each layout is of the form "<sObject API name>-<layout name>", where the layout name is what is shown here. Note however that if either the sObject or the layout is managed, namespaces will be present on the managed entity:

<sObject package namespace>__<sObject name>-<layout package namespace>__<layout name>

If in doubt, you can use a Tooling API query to get the FullName property:

SELECT FullName FROM Layout WHERE Id = '<an id>'

The Id is in the URL for each layout's detail page.
