Error in installed plugins page when installed a fluentd plugin from a locally created gem

[tamsel]

The error was because the latest version value was nil.

Error:
ActionView::Template::Error (no implicit conversion of nil into String):
latest_version: { label: "#{t("plugins.common.latest_version")}", sortable: true },
is_latest_version: { label: "" }
},
items: #{plugins_json.html_safe},
filter: null
}
}

Sorry for the delay.
I will check code this week or next week.
