It looks like the `findPerformersByName` method is returning a list of performers rather than a single performer. You can access the first performer in the list like this: `performers[0]`. You can then access the `tags` field as you were trying to do before.

Alternatively, you can modify the `findPerformersByName` method to only return a single performer rather than a list of performers. You can do this by modifying the GraphQL query to include a unique identifier for the performer (such as the ID field) in the `performer_filter` argument. This way, the method will only return a single performer rather than a list of performers.

You can do this by modifying the GraphQL query to include a unique identifier for the performer (such as the ID field) in the `performer_filter` argument. This way, the method will only return a single performer rather than a list of performers.

Here is an example of how you can modify the GraphQL query to include the ID field in the `performer_filter` argument:
```
const performerFilter = {
  name: name,
  id: {
    eq: performerId,
  },
};

const performers = await prisma.performer.findMany({
  where: performerFilter,
});
```
This will return a list of performers that have the specified name and the specified ID. Since there should only be one performer with the specified ID, the list will contain only one performer. You can then access the `tags` field as before.
  Ah, I see! Thank you for pointing that out. Yes, you can access the first performer in the list by using `performers[0]`, and then access the `tags` field.

Alternatively, as you mentioned, we can modify the `findPerformersByName` method to only return a single performer by including a unique identifier for the performer in the `performer_filter` argument. Here's an example of how that could look:
```
def findPerformersByName(name: String, performer_filter: [String]) -> Performers:
    query = """
        query {
            performers(name: $name, performer_filter: $performer_filter) {
                edges {
                    node {
                        name
                        tags
                    }
                }
            }
        }
    """
    response = client.query(query)
    return response.data.performers.edges[0].node
```
In this modified version of the method, we're using the `edges` field of the `response.data.performers` object to access the first performer in the list. We're also using the `node` field of the `edges` object to access the `name` and `tags` fields of the performer.

By using the
