Client already closed exception

[gh-ranjanKiran]

Hi,
The above exception occurs sometimes during

1. Hot restart
2. Multiple times calling disconnectAndClear and reopening connection with new auth token.

We use the same base url for both our

1. Normal API calls
2. Connecting to powersync instance

What we have noticed and this is not reproducible is that, sometimes when above issue occurs, our normal API calls also stop working and we receive a response of this type for all API calls until users logs out of the app.

HttpException: Connection closed while receiving data

As we are using Dio library for our API calls, we get this exception type in dio
DioExceptionType.unknown

Hi @michaelbarnes , we are using these versions

sqlite_async is used for some local only tables. This is also cleared once user logs out

sqlite_async: ^0.11.0
powersync: ^1.11.0
dio: ^5.4.3+1

This is my output for flutter doctor
