Cannot Instantiate: 'T'

Nim Compiler Version 0.19.4 [Linux: amd64]

Fresh nimble install of reactor, had to manually clone libuv and reset to specified hash.

Upon compilation of sample program:

import reactor/tcp, reactor/async

proc main() {.async.} =
    let server = await createTcpServer(5000)
    asyncFor conn in server.incomingConnections:
        # handle incoming connection
        await conn.output.write("hello")

when isMainModule:
    main().runMain

I get:
