Facing issue to use Mongo as persistance storage

[Vishal--Patel]

Describe the bug
We wanted to use workflow core and we started exploring samples provided with mongo, but while running sample18 we are getting below error:

fail: WorkflowCore.Services.BackgroundTasks.WorkflowConsumer[0]

To Reproduce
Steps to reproduce the behavior:

Select sample18 project and run it.

Expected behavior
Sample18 should run successfully.

Additional context
We also tried but that also did not help:

// if (!BsonClassMap.IsClassMapRegistered(typeof(MyData)))
{
BsonClassMap.RegisterClassMap(cm =>
{
cm.AutoMap();
});
}
