Can't publish file, bishbosh_publishFile function not working, too many output retries : Broken pipe

[chetniks]

Hello,

The function to publish message via file is not working,
bishbosh_publishFile 0 '/topic/something/0' no 'message' is always throwing an error
Tried different backends, changing read latency, as well as to change file path like './message' '/bish-bosh/message' , './var/run/bish-bosh/lock/servers/...' .'/var/lib/bish-bosh/client/servers/...'
Its almost always the same error :
./bish-bosh: 12: read: arg count
Also tried to change bash to /bin/bash and /bin/sh /usr/bin/env sh
The way i run the program is :
./bish-bosh --verbose 3 -- 'publish-sub.test'

publish-sub.test is not important as it comes up that function doesn't work inside any of handlers as i tried it inmost of them.

I have uploaded relevant logs.

On the other hand, publishing message as text (bishbosh_PublishText) function is working properly.

Could you please assist or share an example on how to publish message via file.
