Error in .net core with postgreSQL and graphQL to get json column for all records

I am using .NET Core 7.0 with PostgreSQL and graphQL. I am getting an error when I try to get all records from the database using the below code. When I try to get a single record then it is working fine.

Error:

The source ‘IQueryable’ doesn’t implement ‘IAsyncEnumerable<Vcp.Doctors.Gql.Models.ProviderInformation>’. Only sources that implement ‘IAsyncEnumerable’ can be used for Entity Framework asynchronous operations.

I have a JSON field for the KnownByOtherName column of my PostgreSQL database.

This is the C# code that I am using to get the list of records from the table:

And here is the screenshot of my model class:

Help me to fix this issue.
