SDK Parse 1.0.26 not usable - boolean expression must not be null

[jeansebastienZ]

Hi,

I'm making a new topic , as the old one get no answer and it still problematic in order to use the last SDK .
Issue on Android

1. Create a new project
2. Basic initialisation :

 Parse().initialize(
        MyParse.applicationId,
        MyParse.serverURL,
        masterKey: masterKey,
        clientKey: clientKey,
        debug: true,
        liveQueryUrl: liveQueryUrl,
        autoSendSessionId: true);

3)[ERROR:flutter/lib/ui/ui_dart_state.cc(166)] Unhandled Exception: Failed assertion: boolean expression must not be null

Where is the problem ? seem to refer to :
ParseHTTPClient.send (package:parse_server_sdk/src/network/parse_http_client.dart:40:14)

Using parse_server_sdk: 1.0.21 with the same code , works perfectly . However 1.0.21 is not usable if you need parse live query and subscription.

Can you try to dig and find out whats the problem please ?

Hey Can you provide more details around exactly where this error is being triggered from? Is this on the health check when the app starts, or is this a ParseObject, Live etc etc. Thanks

Hello,

It is on the health check when the app start :

  Parse().initialize(
        MyParse.applicationId,
        MyParse.serverURL,
        masterKey: masterKey,
        clientKey: clientKey,
        debug: true,
        liveQueryUrl: liveQueryUrl,
        autoSendSessionId: true);

    final ParseResponse response = await Parse().healthCheck(); 

[phillwiggins]

Something sounds off here. I am pretty much the exact initialisation on app start with no faults. What version of the lib are you using? Have you tried deleting all build folders? I'm wondering if there's some old lib files causing this issue.

Can you also send across the logs showing the issue as well please.

I post all my dependencies, if something is interfering, don't know :

http: ^0.12.0+4
shared_preferences: 0.5.7+1
connectivity: ^0.4.8+5
web_socket_channel: ^1.1.0
parse_server_sdk: 1.0.26

I would not find out the problem was a version related if #282 did not get the same problem .

Very strange. I cannot replicate this issue.

Can you try adding a persistant storage option?

coreStore: await CoreStoreSembastImp.getInstance()

Add this to the Parse.initialize() method?

[jeansebastienZ]

Hello Phill ,

Parse().initialize(
MyParse.applicationId,
MyParse.serverURL,
masterKey: masterKey,
clientKey: clientKey,
debug: true,
liveQueryUrl: liveQueryUrl,
autoSendSessionId: true,
coreStore: await CoreStoreSembastImp.getInstance());

Works , can you explain me why ? I trie on a new project and on my old , and for both with CoreStoreSembastImp.getInstance() it work . Thanks you for this , if you think you know why let me know then i'll close this one .

[phillwiggins]

It should work by default with just Sembast but it looks like a bug might have been introduced. We allowed users of the SDK to decide if they want to use mobile first storage (SharedPrefs etc) or platform independent storage, such as Sembast. It looks like if one isn't selected, no default is set. Although this isn't the case on my own project.

Inside parse_core_data.dart a default CoreStore should be set.

    _instance.storage ??=
        store ?? await CoreStoreSharedPrefsImp.getInstance(password: masterKey);

Ok indeed i see , should be corrected for future users , basically , i didn't expect you to answer that fast , so thanks , you saved my day . Send paypal i'll make a small donation . Have a nice day .

[phillwiggins]

Your welcome. If you would like to donate anything , please do so to the Parse groups donations. https://opencollective.com/parse-server Thank you.

@phillwiggins
This is just an idea:
The password for the default CoreStore is masterKey. And masterKey should be null in every published app. This might cause the assertion to fail.
I have not tested it, but it might be better to use the password 'flutter_sdk'. As this one is used inside the getInstance block as a default.

[phillwiggins]

Sounds like a logical solution?

Unfortunately I have at the moment no time to give this a try. I will do so in several hours.
If this fixes the issue, it should be a good solution.
Additionally we should encourage programmers to use a custom and random password. By telling them in the Readme. As a default password is never the best solution and it is easy to miss.
