gui-v2 (wasm) throws runtime error on repeated connection attempts #1177

I am seeing runtime error when trying to launch gui-v2 (wasm) on the latest main branch, possibly from Add BackendConnection::serviceUidFromName() change.

@jpetrell is this repeatable for you? I can't reproduce it locally.

Ok false alarm, had VRM two-way communication disabled for some reason. The error seems real real, but should not happen during the normal usage, only if repeated connection attempts fail.

Thanks for testing! That is really helpful, prompted me to go back and re-check my configs. :smile:

possibly from Add BackendConnection::serviceUidFromName() change.

Not related to ^^, also happens with earlier v0.3.1 release.
