void50 commented 6 days ago

Good afternoon.

I am trying to connect to your nodejs demo project that was creation according to the inctruction (self host): https://github.com/powersync-ja/self-host-demo/tree/main/demos/nodejs

Created base, demo-backend, demo-client, powersync-service. Docker_Desktop_c1Ng02AxOM

Demo-client is working for sync!

FLUTTER

app_config.dart

class AppConfig {
  static const String backendUrl = 'http://localhost:6060'; //nodejs
  static const String powersyncUrl = 'http://localhost:8080';
}

powersync.dart DKeZUXdafk dmK2saxL3e


     PowerSyncCredentials(
        endpoint: AppConfig.powersyncUrl,
        token: parsedBody['token'],
      );

EXCEPTIOIN

When I try to connect your example FlutterProject. I get follow exeption:

What could be the problem?

rkistner commented 6 days ago

The test request has a json encoding issue (appears like the data is escaped when it shouldn't be).

The Flutter response indicates it is hitting Apache, instead of the powersync-service. Any idea why that would be?

then there 41 SyncResponseException.fromStreamedResponse was a problem

 Sync error: Configuration error
flutter: FormatException: Unexpected character (at character 1)
<!DOCTYPE HTML PUBLIC "-//IETF//DTD HTML 2.0//EN">

BUT I realised if Flutter's response doesn't hit Appache, then everything will be fine...

I'll keep trying... for now....

I changed the port of powersync-service ,for quicly, to 8383 and everything worked!!!

That's great It worked a lot

THANKS
