Debugging

Generally the Playground gives a lot of information about what's happening, but when that is insufficient, you have other options.

Logging the raw request and response from LLM calls​

You can provide a rawRequestResponseHandler to the agent to log the raw request and response from the LLM.

You could use this to log the request and response to a table, or use console logs with Log Streaming to allow debugging and searching through Axiom or another logging service.

const supportAgent = new Agent(components.agent, {
  ...
  rawRequestResponseHandler: async (ctx, { request, response }) => {
    console.log("request", request);
    console.log("response", response);
  },
});

Inspecting the database in the dashboard​

You can go to the Data tab in the dashboard and select the agent component above the table list to see the Agent data. The organization of the tables matches the schema. The most useful tables are:

  • threads has one row per thread
  • messages has a separate row for each CoreMessage - e.g. a user message, assistant tool call, tool result, assistant message, etc. The most important fields are agentName for which agent it's associated with, status, order and stepOrder which are used to order the messages, and message which is roughly what is passed to the LLM.
  • streamingMessages has an entry for each streamed message, until it's cleaned up. You can take the ID to look at the associated streamDeltas table.
  • files captures the files tracked by the Agent from content that was sent in a message that got stored in File Storage.

Troubleshooting​

Circular dependencies​

Having the return value of workflows depend on other Convex functions can lead to circular dependencies due to the internal.foo.bar way of specifying functions. The way to fix this is to explicitly type the return value of the workflow. When in doubt, add return types to more handler functions, like this:

 export const supportAgentWorkflow = workflow.define({
   args: { prompt: v.string(), userId: v.string(), threadId: v.string() },
+  handler: async (step, { prompt, userId, threadId }): Promise<string> => {
     // ...
   },
 });

 // And regular functions too:
 export const myFunction = action({
   args: { prompt: v.string() },
+  handler: async (ctx, { prompt }): Promise<string> => {
     // ...
   },
 });
