Description
I'm building a tutorial for Parse Serve (using Back4app) and ran into this issue on SKD for Flutter.
New Issue Checklist
- [x ] I am not disclosing a vulnerability.
- [ x] I am not just asking a question.
- [ x] I have searched through existing issues.
- [x ] I can reproduce the issue with the latest version of Parse Server and the Parse Flutter SDK.
Issue Description
I tested the following code:
void main(List<String> arguments) async {
// String appId = 'appIdCorrect';
// String clientKey = 'clientKeyCorrect';
String appId = 'appIdWrong';
String clientKey = 'clientKeyWrong';
String keyParseServerUrl = 'https://parseapi.back4app.com/';
var parse = await Parse().initialize(
appId,
keyParseServerUrl,
clientKey: clientKey,
autoSendSessionId: true,
debug: true,
);
print(
'Parse().hasParseBeenInitialized(): ${parse.hasParseBeenInitialized()}');
if (parse.hasParseBeenInitialized()) {
var response = await parse.healthCheck();
print('response.success: ${response.success}');
print('Bach4App: Ok');
} else {
print('Bach4App: Not Ok');
}
}Steps to reproduce
Create a pure standard Dart project with VSCode
Create a basic project in back4app and write down the appId and clientKey.
Copy the code above to your Dart project and enter the correct appId and clientKey and then a wrong value.
Run the Dart project with:
$ dart bin/learning_about_b4a_dart.dart
Actual Outcome
If I put the correct appId and clientKey values I get:
Parse().hasParseBeenInitialized(): true
response.success: true
Bach4App: Ok
But if I put the wrong appId and clientKey values I get:
Parse().hasParseBeenInitialized(): true
Unhandled exception:
type 'Null' is not a subtype of type 'int'
#0 buildErrorResponse (package:parse_server_sdk/src/objects/response/parse_error_response.dart:8:25)
#1 _ParseResponseBuilder.handleResponse (package:parse_server_sdk/src/objects/response/parse_response_builder.dart:18:14)
#2 handleResponse (package:parse_server_sdk/src/objects/response/parse_response_utils.dart:8:31)

#4 main (file:///home/catalunha/myapp/learning_about_b4a_dart/bin/learning_about_b4a_dart.dart:20:20)
There was an error when calling: await parse.healthCheck();
Expected Outcome
The return from await parse.healthCheck() is a Future so I would expect a parseResponse.success = false as I entered incorrect appId and clientKey values. But actually I get an error in the SDK.
🇧🇷
Because in my tutorial the user can change the appId and clientKey to test my tutorial.
So if it reports a wrong appId and clientKey I have an SDK error and not a parseResponse.success=false return.
