Getting Error While installing plugin in logstash-7.0.1 about logstash-output-slack

[odlevakp]

Any news regarding this issue?
Someone on logstash 7 not having this problem?

When we tested migration to ELK 7, this is the only issue we encountered and it's currently holding back our update.

I've found an alternative to push messages to mattermost. In my case it's enough.

http
{
http_method => "post"
url => "https://mattermost.*/hooks/********"
format => "message"
message => '{"text":"%{@timestamp} %{[beat][hostname]} %{payload}"}'
}

I am not familiar with gem/ruby, but it seems that 'bundle update' is a part of ruby package dependency management. From a little digging, it also looks like logstash has its own version of ruby installed in the same tree. What would be the correct way to bootstrap the ruby/gem/bundle environment so that it will work with the logstash installed versions and allow 'bundle update' to be run? Also, would it be correct to run 'bundle update from the logstash home (/usr/share/logstash for me)?

Having the same issue when building Logstash 7.3.1 for Docker :(

I have this issue too. Is there any fix?

We're facing this problem on logstash 7.3 as well. Any ideas?

For me it worked when I removed public_suffix dependency check for < 1.5.0.

After some initial testing, the messages are sent to slack, although, I wouldn't consider it a fix.

Clone and edit spec file.

git clone https://github.com/logstash-plugins/logstash-output-slack.git

cd logstash-output-slack/

vim logstash-output-slack.gemspec

Update version (not needed) and remove public_suffix dependency.

-  s.version         = '2.1.1'
+  s.version         = '7.0.0'

-  s.add_runtime_dependency "public_suffix", "< 1.5.0"
+  s.add_runtime_dependency "public_suffix"

Build and install as a plugin.

bundle install
gem build logstash-output-slack.gemspec


cd /usr/share/logstash/

bin/logstash-plugin install \
~/logstash-output-slack/logstash-output-slack-7.0.0.gem

Another option to send messages to slack using http output and define post json content using mapping:

http {
    http_method => "post"
    url => "${SLACK_WEBHOOK}"
    format => "json"
    mapping => {
        channel => "#channel"
        text => "%{level_name} %{channel}: %{message}"
        blocks => [
            {
                type => "section"
                text => {
                    type => "mrkdwn"
                    text => "*%{level_name}, %{channel}*: %{message}"
                }
            }
        ]
        attachments => [
            {
                title => "Kibana"
                title_link => "https://kibana/something"
                color => "#ddd"
            }
        ]
    }
}```
