ParseLiveListWidget doesn't work

[yp19]

I am using following server and client versions
"parse-server": "^4.5.0" (server)
parse_server_sdk_flutter: ^3.0.0 (client)

Flutter log contains following lines (mostly)

I/flutter ( 8004): LiveQuery: : Socket opened
I/flutter ( 8004): LiveQuery: : ConnectMessage: {op: connect, applicationId: appid, sessionToken: r:token}
I/flutter ( 8004): LiveQuery: : Done
I/flutter ( 8004): LiveQueryReconnectingController: Retrytimer set to 10000ms
I/flutter ( 8004): LiveQueryReconnectingController: LiveQueryClientEvent.DISCONNECTED

Server log contains following lines (mostly)

info: Client disconnect: undefined
error: Can not find client undefined on disconnect

Flutter parse init:

await Parse().initialize(
    keyParseApplicationId,
    keyParseServerUrl,
    debug: true,
    liveQueryUrl: keyLiveQueryUrl,
    coreStore: await CoreStoreSharedPrefsImp.getInstance(),
    autoSendSessionId: true,
  );

Note: The LiveQuery is working with Javascript code.

@RodrigoSMarques Could you help with this. Thanks in advance.

It is not a problem in LiveQuery because I am using it in two projects without errors.

Is the problem using ParseLiveListWidget?

I don't know what this widget does.

@fischerscode do you know what it can be?

It can’t be ParseLiveListWidget I’m using it and it works well for me.

I’m using
"parse-server": "^4.5.0" (server)
parse_server_sdk_flutter: nullsafety (client)

Please 'inspect' your web app and have a look at the network traffic (instructions for chrome). Your problem might be caused by CORS.

@yp19 @pastordee
Please note that there is a live query bug in version 4.5.0. There might appear problems if you have multiple live queries running at once. I recommend using a custom version of 4.5.0 that contains the fix that was merged to master in 7341. If you want a simple solution, you could use the version I use. It has been running as a the back end for a beta app for almost a month now.

Okay thanks will check it out tonight

@fischerscode Thanks for the reply.

I tried your suggestion with flutter web. I have enabled CORs. It is working fine with flutter web.

But it is not working with flutter android, getting the same log repeatedly in adb log:

I/flutter (18510): LiveQueryReconnectingController: LiveQueryClientEvent.DISCONNECTED
I/flutter (18510): LiveQuery: : close
I/flutter (18510): LiveQuery: : Socket opened
I/flutter (18510): LiveQuery: : ConnectMessage: {op: connect, applicationId: appId, sessionToken: r:token}
I/flutter (18510): LiveQuery: : Done
I/flutter (18510): LiveQueryReconnectingController: Retrytimer set to 10000ms
I/flutter (18510): LiveQueryReconnectingController: LiveQueryClientEvent.DISCONNECTED

Any other ideas?

I assume it's not working when build with --release.
In this case, I think it is most likely you missed this step.

@fischerscode
I was not using the --release flag.

Without that permission set, the server was receiving connections, I able to see the log on server, I have posted the server log entries in the description.

But I have added the permission now. It's still has the same problem.

I am using firebase auth, it is working fine and also it able to load the initial list of items with a query. Only the LiveQuery is not working. Something to do with the Websocket connection.

@fischerscode
I have tested with --release flag as well. Seeing the same log.

I see the server is working from flutter web and regular javascript client.

Any ideas?

@fischerscode Friendly ping

@yp19
Sorry, I think my GitHub notification did not work for a while.

Does the same problem appear on mobile?

Stuff, I would try:

• specify a client key
• make a minimal test project
• run a parse-server locally (rules out internet problems)
