# Get Objects of Type

| ## Step Details |
| --- |
| **Introduced in Version** | 4.0.0 |
| **Last Modified in Version** | 5.12.0 |
| **Location** | Data |

The **Get Objects of Type** step is used to extract objects of a user-specified data type from a List of Objects. The step does so via the Source List Input which allows users to Input the List that will be filtered by the step. The other utilized Input in this step is the Objects of Type drop-down, wherein users choose the type of Object they are trying to filter. The step then takes the filtered Objects and compiles them into a new List. Note: The step offers an additional path to handle the event of the step returning no results.

## Common Errors

### Value cannot be null

If the Objects of Type field is not set, an error will occur. To correct this, ensure that the Object of Types field is set to a data type.

#### Exception Message:
