HTTP Monitor configuration

Hello friends

I use Grylog Version 3.1
I want to configure HTTP Monitor
I get the following error while importing content_pack.json file
//* Error importing content pack, please ensure it is a valid JSON file. Check your Graylog logs for more information.
Null id at [Source: org.glassfish.jersey.message.internal.ReaderInterceptorExecutor$UnCloseableInputStream@33bc6cf6; line: 474, column: 1] (through reference chain: org.graylog2.contentpacks.model.AutoValue_LegacyContentPack$Builder[“id”]) *//

please guide me

I guess that the version you are using - of the content pack - is not compatible with the Graylog version.

It is very likely that the creator of the contentpack did not (yet) updated it to the new Content packs in Graylog 3.x

Hi jon infinite thank you
