Error running app

I compiled using rebar3.
All supported dependencies are installed
When I try to run the app, it gives following error
>>> lsb_release -a
No LSB modules are available.

Hello,
Is the problem related to any query ? I never faced this problem and we are using the library in lot of big projects.
Silviu
I compiled it using rebar3 and wanted to run few test cases. So I loaded the code using
/rebar3 shell --apps erlcass
It fails at this point itself with the floating point error.
However I checkout v3.2.6 , compiled using exact same steps and loaded it into shell. It works perfectly well. This is amazon aws t3a.medium instance. 64 bit.
It could be the .so file has some issues? the error is really not descriptive. thus commented here.
It might be a bug into the native driver between last master and 3.2.6 there is a major update into the native driver from datastax.
It's crashing only by starting the app without running any query ?
Silviu
yes. just by compiling and trying to start the app.
./rebar3 compile
./rebar3 shell --apps erlcass
my bad. after specifying a config it works.
./rebar3 shell --apps erlcass --config /home/ubuntu/data/erlcass/sys.config
looks like it was dividing contact_points somewhere. and this list by default was empty.
@pankajsoni19 Can you please provide me the config that cause the crash ? I want to fix this to return an error or something instead
Silviu
while i was running the 3.2.6 branch , I didn't specify config, it seemed to load the app. just that it said connection failed. So I switched to 4.0.0 branch and ran the same command, here it crashed with the floating point error. I am guessing the default empty endpoint point list would be an issue. as floating point error means division by 0 [ atleast what google says ]
./rebar3 shell --apps erlcass
So I guessed maybe the code needs config and can't boot without it. I specified the config later and it started well. BTW I was trying to connect with scyllaDB rather than cassandra. You should mention that your driver works for it too.
Ok Thanks I will look when I have some time in starting the app without any config
This seems fixed in master
