Custom function that uses enum fails in compilation and test mode is unavailable - URGENT

[chesskiss]

Can we access your project?

• I give permission for members of the FlutterFlow team to access and test my project for the sole purpose of investigating this issue.

Current Behavior

The test does not compile. See the error below.

Please see the recording I made below that recreates the error.

Expected Behavior

Should compile and run in test mode

Steps to Reproduce

1. Create a custom function that takes a string list and returns an enum list. You can leave the function empty and return an empty enum list.
2. Create a widget that calls it

Reproducible from Blank

• The steps to reproduce above start from a blank project.

Environment

- FlutterFlow version: v4.183+ (synced)

- Operating system and version affected: MacOS Sonoma 14.5 (23F79)

Additional Information

I intend to launch this app in the upcoming days, and now the project is stuck because I cannot test it properly. This is the most crucial time of my startup, so it is very urgent for me to resolve this. If I don't, I'll just copy the code to a local environment, and will, unfortunately, have to continue this project without FF (which was very convenient until now)

For some reason, it doesn't upload the video?...

Hi there!

I wasn’t able to replicate the error in a new blank project. Here’s what I did:

1. Created an enum with two values.

2. Created a function that receives a list of strings and returns an empty list of enums.

3. Created a button that calls the function and returns the number of enums in the list.

@Alezanello please see the video below on how I did it (I update firestore):

@Alezanello Ok seeing I'm not getting any answers, which I feared would happen since you didn't change the status back or try again after my clarification, I'll have to repost it again.

I'm sorry for the late response, I'll try to replicate what you have in the video just need a little more patience.
I'll close the new post as duplicated and follow this as the original one

I found the issue, though a bit late—it’s related to how custom functions are serializing enums. As a workaround, I was able to achieve the desired outcome using custom actions instead of custom functions. Here’s the code I used:

extension EnumTestExtension on EnumTest {
  String serialize() {
    return this.toString().split('.').last;
  }
}

Future<List<EnumTest>> enumTestAction(List<String> list) async {
  return [];
}

With this approach, I successfully created the document in Firestore by using the action output result list as the field value.

So first you create an extension of the enums to serialize the strings and then execute the function

here is the public project in case you want to clone it or check it: https://app.flutterflow.io/project/qa-1817-nqezfl

@Alezanello Thank you very much!!! I will try it!
