Dart Runtime error on local functions 'Request body size exceeds the size limit.'

Hello,

I'm trying the local functions dev env. It's very useful.

I tried python-3.9 and it works out of the box But I can't get dart runtimes working. I tried dart-3.1 and dart-3.3

I've updated the docker compose .env

TypeScript

_APP_FUNCTIONS_RUNTIMES=node-16.0,php-8.0,python-3.9,ruby-3.0,dart-3.3,dotnet-3.1,dart-3.1

and downloaded the runtimes docker pull openruntimes/dart:v3-3.1 (tried v4-3.1 as well) docker pull openruntimes/dart:v3-3.3

then restarted the containers

Function is very basic:

TypeScript

import 'dart:async';

// This Appwrite function will be executed every time your function is triggered
Future<dynamic> main(final context) async {
  return context.res.json({
    'motto': 'Build like a team of hundreds_',
    'learn': 'https://appwrite.io/docs',
    'connect': 'https://appwrite.io/discord',
    'getInspired': 'https://builtwith.appwrite.io',
  });
}

The functions are well created but when I request the http://localhost:3000/ I get the following error:

TypeScript


Request body size exceeds the size limit.

#9      _SyncStreamControllerDispatch._sendData (dart:async/stream_controller.dart:784)
#10     _StreamController._add (dart:async/stream_controller.dart:658)
.....

Am I missing something ?

TL;DR

Developers facing Dart Runtime error "Request body size exceeds the size limit" when trying to run local functions. They have updated the Dart runtimes in docker compose and restarted containers but still encountering the issue. Solution: Adjust the maximum request body size setting in the Dart server config to handle larger requests.
