```go lines theme={null}
switch functionCallOutputItemOutputUnion1.Type {
	case components.FunctionCallOutputItemOutputUnion1TypeInputText:
		// functionCallOutputItemOutputUnion1.InputText is populated
	case components.FunctionCallOutputItemOutputUnion1TypeInputImage:
		// functionCallOutputItemOutputUnion1.FunctionCallOutputItemOutputInputImage is populated
	case components.FunctionCallOutputItemOutputUnion1TypeInputFile:
		// functionCallOutputItemOutputUnion1.InputFile is populated
}
```
