Toolbox Service auto-discovery shows “Skipped” but still logs 201 Created

[GHkrishna]

What

Following docs, I am unable to receive any response from the agent. I suspect this step [Cloudflare account with Workers enabled]. Since I didn't find any docs on where exactly we add it, or even whether it's necessary.

Also, I've changed the code a bit to create open-ai agent instead of the default anthropic.

The code I've changed:

.
.
.
case "openai":
			 provider = createOpenAI({ apiKey: env.AI_PROVIDER_API_KEY });
  			 model = provider.languageModel(env.MODEL_ID);
			 break;
.
.
.
