Received implausibly large message from tcp error

[wybgithub]

When I execute the following command
wyb89@ubuntu:~/soft/firmament-master$ ./build/src/coordinator --listen_uri tcp:localhost:8080 --task_lib_dir=./build/src
and then type in "localhost:8080" in my browser
I get following errors

I do not know why. Were my operations wrong? Could you please give me some guidance?

Hi @wybgithub,

Sorry for the delay, we must have overlooked this issue.

It looks like you're passing port 8080 as the port for Firmament's internal protobuf RPCs, rather than as --http_ui_port. If you try to send an HTTP request to the internal RPC port, Firmament will try to deserialize the request as an RPC and get confused. You should use a separate port (default is 9999) for the internal RPCs (--listen_uri) and the web UI (--http_ui_port).
