## Common Errors

### Guid string should only contain hexadecimal characters

If the input string contains characters other than hexadecimal characters, an error will occur. To resolve this, ensure that the input only contains the letters A - F and numbers 0 - 9.

#### Exception Message:

```csharp
Exception Stack Trace: DecisionsFramework.Design.Flow.ErrorRunningFlowStep: Error running step Get Guid From String 1[GetGuidFromString] in flow [Flow 2]: Exception invoking method GetGuidFromString on class StringSteps
 ---> DecisionsFramework.LoggedException: Exception invoking method GetGuidFromString on class StringSteps

```

---

### Guid should contain 32 digits with 4 dashes (xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx)

If the input contains under or more than 32 characters, an error will occur. To correct this, ensure that there is only 32 characters.

#### Exception Message:

```csharp
Exception Stack Trace: DecisionsFramework.Design.Flow.ErrorRunningFlowStep: Error running step Get Guid From String 1[GetGuidFromString] in flow [Flow 2]: Exception invoking method GetGuidFromString on class StringSteps

   --- End of inner exception stack trace ---
```

---

### Value cannot be null

If the input value is null, an error will occur. To resolve this, ensure that the value is correctly mapped/entered.

#### Exception Message:

```csharp
Exception Stack Trace: DecisionsFramework.Design.Flow.ErrorRunningFlowStep: Error running step Get Guid From String 1[GetGuidFromString] in flow [Flow 2]: Exception invoking method GetGuidFromString on class StringSteps
 ---> DecisionsFramework.LoggedException: Exception invoking method GetGuidFromString on class StringSteps
 ---> System.ArgumentNullException: Value cannot be null. (Parameter 'input'

 at DecisionsFramework.Design.Flow.FlowStep.Start(String flowTrackingID, String stepTrackingID, FlowStateData data, AbstractFlowTrackingData trackingData, RunningStepData currentStepData)
   --- End of inner exception stack trace ---
```

---

### Unrecognized Guid format

If the value is an empty string, an error will occur To resolve this, ensure that there is a value entered in the Value field.

#### Exception Message:

```csharp
Exception Stack Trace: DecisionsFramework.Design.Flow.ErrorRunningFlowStep: Error running step Get Guid From String 1[GetGuidFromString] in flow [Flow 2]: Exception invoking method GetGuidFromString on class StringSteps
 ---> DecisionsFramework.LoggedException: Exception invoking method GetGuidFromString on class StringSteps
