How to handle a database connection from multiple Service Bus queue message triggers within Azure Functions?

Question

I am using Azure Functions with a Service Bus queue message trigger to receive a queue message and process it to store in Azure SQL using Entity Framework. This does process some queue messages properly but for some queue messages, it throws the following exception:

Result: An exception occurred while iterating over the results of a query for context type 'webhooksecretply.DatabaseModels.igdbapi.IGDBAPIAppContext'. System.InvalidOperationException: There is already an open DataReader associated with this Connection which must be closed first.

For reference, the database connection is opened through the following line:

Program.cs

s.AddDbContext
