Plugins Not Working

Describe the bug
After enabling plugins (tried with Klarna Shopping and my previously working custom plugin), and typing in the chat, chat will show this error

Unable to generate bot response.

thanks @raffertyuy When you say latest code, are you referring to the latest release, or the latest commit on main? Can you please point me to the exact commit you are using?

Hi @momuno, it's the latest commit on the chain as of yesterday.
Should be this one: ccf79dc

Update: Issue also exists in v0.8, but works fine on 0.7.1.

Thank you @raffertyuy. We were able to reproduce and are working on reverting the version bump. (Tested that plugins do work on commit prior to the version bump). We will then look into what caused the problem.

It seems that SK now expects json with camel casing and CC follows OpenAi’s documentation, snake case.
When I removed the attributes forcing snake case in WebSearcher plugin, SK could deserialize and import, but CC breaks because it’s expecting the previous format.

A temporary workaround is adding both camel and snake properties to PluginShared.PluginManifest.

    /// <summary>
    /// Manifest schema version
    /// </summary>
    [JsonPropertyName("schema_version")]
    public string p1 => SchemaVersion;
    public string SchemaVersion { get; set; } = "v1";

Thank you for bringing this issue up.

This should now be fixed with PR #624

[raffertyuy]

Confirmed working on my custom plugin. Klarna shopping isn't working still though, but different "Oops..." error.

[glahaye]

Another fix is coming for Klarna. It will be in when this PR is merged: #626
