The 'Options' field is not properly escaped, fails when " some_key_without_value: " is present

[sirkubax]

It seems, that when in the templates/slack-message.ftl the value ${executionData.argstring} is a
{ 'key': value, 'key2': value, "some_key_without_value": }

Options: app: promo system_version_file: stg_default version_in_system_version_file: version_unknown diff: --diff dont_enable_after_deploy: false dry_run: disable_nagios_probe: True version_override: 0.9.926 verbose: -v

a dry_run: is not empty, it contains ' ' whitespace :) yet it should be escaped...

The slack reject the output.
Is this a Slack issue, or a rundeck-slack plugin escaping issue?

This fixes the problem on the 'template level' :)

<#if (executionData.argstring)?has_content>
    ,{
      "title": "Options",
-      "value": "${executionData.argstring}",
+      "value": "${executionData.argstring?js_string?replace(":", "A")}",
      "short": false
    }
</#if>

Result:

Options: app: promo system_version_file: stg_default version_in_system_version_file: version_unknown diff: --diff dont_enable_after_deploy: false dry_run: disable_nagios_probe: True version_override: 0.9.926 verbose: -v

(do not ask me, why the replacment does not contain "A")

At Slack channel:

Options

-app promo -diff --diff -disable_nagios_probe True -dont_enable_after_deploy false -dry_run " " -system_version_file stg_default -verbose -v -version_in_system_version_file version_unknown -version_override 0.9.926
