To pass an array of strings to a function in Voiceflow, it's important to understand how data is handled within functions and variables. If you're encountering an error stating the array is empty, it might be due to how the array is being passed or initialized. Here are some key points to consider:
- Variables used in the Code Step must already exist before they can be referenced within the Code Step. This means you need to ensure your array variable is created and properly initialized in your Voiceflow project before attempting to pass it to a function.
- The function step in Voiceflow accepts data through an arguments object,
args, which contains the data passed into the function. If you're working with arrays, ensure that the array is correctly passed to this object.
- Voiceflow functions conclude by returning an object that can include output variables, a next command for navigation, and trace commands for debugging. Make sure your function is structured to handle array data correctly and return the expected results.
If you're still facing issues, double-check the initialization and passing of your array variable, ensuring it aligns with Voiceflow's handling of variables and function data. For more detailed guidance on working with variables and functions in Voiceflow, you might find these resources helpful:
- Introduction to Variables in Voiceflow
- Working with Functions in VoiceflowFunctions only accept strings right now, so you need to convert the array into a string. To do this, you need to JSON.stringify(varName) before hand and then pass in the varName to the function. Within the function, use JSON.parse(functionVarName) to turn it back into an object/array.
