Azure durable function Microsoft.Azure.WebJobs.Host: Error indexing method

问题

I am using Azure durable function with Service Bus bindings . This project was working fine earlier but suddenly not sure what happened I am getting following exception "Microsoft.Azure.WebJobs.Host: Error indexing method "

I am using following stack

1. VS 2017

2.Azure Function 2.0

3. Microsoft.Azure.WebJobs.Extensions.DurableTasks 1.7.1

4. .Net core 2.2

5. C#

I tried to by creating a new solution and manually copy the relevant files under new azure durable function project. Then it is working .

But I am not able to run the same from my existing project solution.

Anyone facing this issue ?
