runtime error

[ssow]

Hi,

I'm facing a runtime error related to the websocket component.

Error in process <0.226.0> on node 'erlangpl@127.0.0.1' with exit value:
{undef,[{crypto,sha,
[<<"DhX4I0c+u60EPDe8ETlV2w==258EAFA5-E914-47DA-95CA-C5AB0DC85B11">>],
[]},
{cowboy_websocket,websocket_handshake,3,
[{file,"src/cowboy_websocket.erl"},{line,142}]},
{cowboy_protocol,execute,4,
[{file,"src/cowboy_protocol.erl"},{line,522}]}]}

For your information, the node running on centos 7 with erlang/OTP 21

I've tried to recompile the tool but it fails with the following error 👍 error

/production/factory/erlangpl/node_modules/elm-format: Command failed.
Exit signal: SIGABRT

Any suggestion appreciated.

Thank you

Hello @ssow
I can try to help with the first error on CentOS 7, which indicates you do not have the crypto application installed in your system. Try the following command sudo yum install erlang-crypto and then try running the tool again.

Hello @michalslaski

I've installed the complete esl-erlang.x86_64 (21.3.7-1) package, which includes crypto-4.4.2.
If this version is ok than the problem is somewhere else, I guess
Thank you.

@ssow OTP 20 removed the previously deprecated crypto:sha/1 function in favour of crypto:hash/2. It seems this project deserves an upgrade of the underlying cowboy library and a new release :)

Thanks so much for reporting the issue, which somehow went unnoticed for a long time!

You're welcome.
When can I expect to see the update ?

Thank you
