## Common Errors

### Value cannot be null (Parameter 'T')

The step requires the fully qualified name for a datatype in order to be used, for example PerformanceTesting.ExampleList. The input is case sensitive and must match exactly

#### Exception Message:

```cpp
Exception Stack Trace: DecisionsFramework.Design.Flow.ErrorRunningFlowStep: Error running step Export Entities to CSV 1[ExportToCSV] in flow [Testing Flow]: Value cannot be null. (Parameter 'T') ---> System.ArgumentNullException: Value cannot be null. (Parameter 'T')
   at DecisionsFramework.Data.ORMapper.DynamicORM.Fetch(Type T, Boolean includeDeleted, Boolean runChecksum)
   at DecisionsFramework.Design.Flow.CoreSteps.DataBase.ExportToCSV.Run(StepStartData data)
   at DecisionsFramework.Design.Flow.FlowStep.RunStepInternal(String flowTrackingID, String stepTrackingID, KeyValuePairDataStructure[] stepRunDataValues, AbstractFlowTrackingData trackingData)
   at DecisionsFramework.Design.Flow.FlowStep.Start(String flowTrackingID, String stepTrackingID, FlowStateData data, AbstractFlowTrackingData trackingData, RunningStepData currentStepData) 
   --- End of inner exception stack trace ---
```

### Could not find the field name

The input for the field name is case sensitive. The casing must match how it is defined for the datatype.

#### Exception Message:

```cpp
Exception Stack Trace: DecisionsFramework.Design.Flow.ErrorRunningFlowStep: Error running step Export Entities to CSV 1[ExportToCSV] in flow [Testing Flow]: could not find field name ---> DecisionsFramework.LoggedException: could not find field name
   at DecisionsFramework.Design.Flow.CoreSteps.DataBase.ExportToCSV.Run(StepStartData data)
   at DecisionsFramework.Design.Flow.FlowStep.RunStepInternal(String flowTrackingID, String stepTrackingID, KeyValuePairDataStructure[] stepRunDataValues, AbstractFlowTrackingData trackingData)
   at DecisionsFramework.Design.Flow.FlowStep.Start(String flowTrackingID, String stepTrackingID, FlowStateData data, AbstractFlowTrackingData trackingData, RunningStepData currentStepData) 
   --- End of inner exception stack trace ---
```
