FlutterFlow 5.0.1 (& 5.0) unable to compile custom action code

[Supertecnoboff]

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

Whenever I try to compile custom action code in FlutterFlow, it does NOT work and also does not state what the code specific errors are. I get the following (general) error:

Unknown error compiling custom code. A common cause is a custom widget or action whose name in the code does not match the name provided in the editor.

Here is my code:

`// Automatic FlutterFlow imports
import '/backend/backend.dart';
import '/flutter_flow/flutter_flow_theme.dart';
import '/flutter_flow/flutter_flow_util.dart';
import '/custom_code/actions/index.dart'; // Imports other custom actions
import '/flutter_flow/custom_functions.dart'; // Imports custom functions
import 'package:flutter/material.dart';
// Begin custom action code
// DO NOT REMOVE OR MODIFY THE CODE ABOVE!

Future getFirstString(String text) async {
// split string by empty spaces and get first string

List words = text.split(" ");
if (words.isNotEmpty) {
return words[0];
} else {
return "";
}
}`

When pressing the Red Cross button, I get an empty list of code errors:

Expected Behavior

1. Create custom action.
2. Write and save custom code.
3. Compile with no errors (or if there are errors, provide me with a list of actual code errors).

Steps to Reproduce

1. Open custom code editor section.
2. Select "+ Add" button and select "Action".
3. Write custom code and set name, return value and parameters.
4. Save custom action.
5. Compile custom action.

Reproducible from Blank

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

Hi @Supertecnoboff,

Thank you for bringing this to our attention. I tried replicating the same action on my end, and interestingly, it compiled correctly.

However, we're currently investigating this further as we've received a few similar reports. An engineer is already looking into it, and we'll keep you posted with any updates.

Thanks again for your patience and for reporting this!

I am seeing a similar behavior with the custom code error.
When I try to build from my local machine (after cloning the GitHub repo) I get the following error. Not sure if they are related.

Launching lib/main.dart on Chrome in debug mode...

@rzambroni Thanks very much for your swift reply, much appreciated. So is this only an issue with FlutterFlow desktop app? (As I have not used the FlutterFlow website in a long time, as the desktop app is much faster to work with). Thanks for your time.

I get the same issue since yesterday. I have custom actions that was not modified and was working for weeks, and now I get this:

"Unknown error compiling custom code. A common cause is a custom widget or action whose name in the code does not match the name provided in the editor."

I am unable to deploy my latest update.

This is a critical issue, please look into this ASAP.

Thanks
