Failing to execute functions: Error Msg:{"error":"type 'Null' is not a subtype of type 'String'"}

yes

Okay it should be the same then

for checking how can i print payload in console or log

Use print() but make sure to pass it a string

here is raw data ```{
"$id": "6452d0f3ce9edca1866d",
"$createdAt": "2023-05-05T23:56:37.807+00:00",
"$updatedAt": "2023-05-06T00:37:35.262+00:00",
"execute": [

],
"name": "func",
"enabled": true,
"runtime": "dart-2.17",
"deployment": "6455a13c9026fb596952",
"vars": [

],
"events": [

],
"schedule": "",
"scheduleNext": "",
"schedulePrevious": "",
"timeout": 15
}```

payload is not printing in response nor in console, print( response.json(payload.toString())); print(payload.toString());

Why are you calling response.json() like that?

Also your error could be happening before the print

not using that

Sorry, what?

just mistakenly copied, trying to see whether it prints on response section or not( or happening something in console).

here is the trace {"error":"type 'Null' is not a subtype of type 'String'#0 start (package:appwrite_function\/main.dart:10)\n#1 main.<anonymous closure>.<anonymous closure> (file:\/\/\/usr\/local\/src\/server.dart:37)\n#2 main.<anonymous closure>.<anonymous closure> (file:\/\/\/usr\/local\/src\/server.dart:36)\n#3 _rootRun (dart:async\/zone.dart:1426)\n#4 _CustomZone.run (dart:async\/zone.dart:1328)\n#5 _runZoned (dart:async\/zone.dart:1861)\n#6 runZonedGuarded (dart:async\/zone.dart:1849)\n#7 main.<anonymous closure> (file:\/\/\/usr\/local\/src\/server.dart:35)\n<asynchronous suspension>\n#8 handleRequest (package:shelf\/shelf_io.dart:138)\n<asynchronous suspension>\n"}

And your file is named main.dart? If so, the problem is around line 10

yes

here is file structure

also change function name (at line 10) main to mainfunc but still giving the same error

Wait line 10 was the function name?

It should be start...

yes its function name define inside ServerAppwrite class

do you mean i have to define main then call this start inside main, right ?

why its printing Environment variables are not set. Function cannot use Appwrite SDK. executing this function in appwirte console ```Future start(final req, final res) async {
final client = Client();

// Uncomment the services you need, delete the ones you don't
// final account = Account(client);
// final avatars = Avatars(client);
// final database = Databases(client);
// final functions = Functions(client);
// final health = Health(client);
// final locale = Locale(client);
// final storage = Storage(client);
// final teams = Teams(client);
// final users = Users(client);

if (req.variables['APPWRITE_FUNCTION_ENDPOINT'] == null ||
req.variables['APPWRITE_FUNCTION_API_KEY'] == null) {
print( "Environment variables are not set. Function cannot use Appwrite SDK.");

} else {
client
.setEndpoint(req.variables['APPWRITE_FUNCTION_ENDPOINT'])
.setProject(req.variables['APPWRITE_FUNCTION_PROJECT_ID'])
.setKey(req.variables['APPWRITE_FUNCTION_API_KEY'])
.setSelfSigned(status: true);
}

res.json({
'areDevelopersAwesome': true,
});
}```

Did you create the variable?

after creating the variable its working fine,

trying to print payload but if i add print statement then function execution is failed saying An internal curl error has occurred within the executor! Error Msg: Operation timed out` other wise its working fine, this is how using print ` print(req.payloads.toString());

req doesn't have payloads. It's payload
