I’m trying to use the example given in Fibery’s markdown documentation [here](https://the.fibery.io/@public/User_Guide/Guide/Markdown-Templates-53/anchor=Mentioning-Entities-and-Users--92511af3-219c-4cf8-be03-dec1a717cdf2) to create a list of all the related entities inside of a rich text field.

When I modify the example script with my database names and try to run it, I get an error.

Here’s the example script:

```auto
{!Books:Id!}
<%
const fibery = context.getService('fibery');
const schema = await fibery.getSchema();
const dbID = schema['typeObjects'].filter((obj) => obj.name == 'Strategy/Book')[0]['id'];
%>
<%= Entity.Books.map((book) => "[[#^" + dbID + "/" + book.Id + "]]").join('\n') %>

```

and here’s my modified version:

```auto
{!Leads:Id!}
<%
const fibery = context.getService('fibery');
const schema = await fibery.getSchema();
const dbID = schema['typeObjects'].filter((obj) => obj.name == 'Test Environment/Lead')[0]['id'];
%>
<%= Entity.Leads.map((lead) => "[[#^" + dbID + "/" + lead.Id + "]]").join('\n') %>

```

and here’s the error:

```auto
Failed to execute Action "Overwrite Description": Cannot read property 'id' of undefined

```

It seems like the object name is undefined.  
I assumed in the example the space was “Strategy” and the database was “Book”, which is the same way mine is structured, is that not actually the case?

Probably you don’t have a type named ‘Test Environment/Lead’ in your schema.

Try logging all the type names from your schema, with a Button that runs this script:

```auto
const fibery = context.getService('fibery')
const schema = await fibery.getSchema()
schema['typeObjects'].map((obj) => console.log(obj.name))

```
