-| `type`          | `String`        | The type of operation (e.g., `Call`, `Create`, etc.), indicating the nature of the trace. |
-| `from`          | `String`        | The address of the account that initiated the operation. |
-| `to`            | `String`        | The recipient address of the call. For `Create` operations, this field is absent as the contract being created doesn't have an address until after the transaction completes. |
-| `gas`           | `String`        | The amount of gas provided for the operation. |
-| `gasUsed`       | `String`        | The amount of gas used by the operation. |
-| `value`         | `String`        | The amount of Ether transferred during the operation. |
-| `output`        | `String`        | The output from the operation. For operations that don't return data or failed, this is typically `0x`. |
-| `input`         | `String`        | The data sent into the call or contract creation. |
-| `error`         | `String`        | An error message if the operation failed. |
-| `revertReason`  | `String`        | The reason provided by a `revert` operation, if applicable. |
-| `calls`         | `Array<Object>` | An array of nested calls made by this operation. This field is recursive, containing further traces of calls made by the traced operation. |
