Add error handling and improve field naming.
The invoke mutation has several issues:
- Missing error handling: The
inngest.sendcall could fail and throw an unhandled exception - Confusing field mapping:
input.textis mapped toemailin the event data, which is misleading - No validation: The mutation returns success regardless of whether the event was actually processed

.input(z.object({
- text: z.string(),
+ email: z.string(),

In src/trpc/routers/_app.ts around lines 5 to 17, the invoke mutation lacks
error handling, uses a confusing field name, and does not validate event
processing. To fix this, rename the input field from text to email for clarity,
wrap the inngest.send call in a try-catch block to handle potential errors, and
return a success response only if the event is sent without exceptions;
otherwise, return an error response indicating failure.

🛠️ Refactor suggestion
Add type safety for event data access.
The function accesses event.data.email without type validation, which could lead to runtime errors if the event data structure doesn't match expectations.
Consider adding type safety by defining an event type interface:
+interface HelloWorldEvent {
+ email: string;
+}
+
export const helloWorld = inngest.createFunction(
{ id: "hello-world" },
- { event: "test/hello.world" },
+ { event: "test/hello.world" },
- async ({ event, step }) => {
+ async ({ event, step }: { event: { data: HelloWorldEvent }, step: any }) => {🤖 Prompt for AI Agents
In src/inngest/functions.ts at line 13, the code accesses event.data.email
without type safety, risking runtime errors if the event structure is
unexpected. Define a TypeScript interface for the event data specifying the
expected shape, including the email property, and use this interface to type the
event parameter. This ensures compile-time type checking and safer access to
event data properties.

Fix duplicate step labels and typo in comment.
Two issues identified:
- Both
step.sleepcalls use the same label "wait-a-moment", which could cause conflicts in the Inngest workflow execution - Typo in line 11 comment: "sunmmary" should be "summary"
Apply this diff to fix both issues:
- //Imagine this is a transcript step
- await step.sleep("wait-a-moment", "10s");
-
- //Imagine this is a sunmmary step
- await step.sleep("wait-a-moment", "5s");
+ //Imagine this is a transcript step
+ await step.sleep("transcript-step", "10s");
+
+ //Imagine this is a summary step
+ await step.sleep("summary-step", "5s");Committable suggestion skipped: line range outside the PR's diff.

In src/inngest/functions.ts lines 9 to 12, fix the duplicate step labels by
giving each step.sleep call a unique label to avoid conflicts in the workflow
execution. Also, correct the typo in the comment on line 11 by changing
"sunmmary" to "summary".

Fix payload mismatch between mutation and Inngest function.
The mutation is sending {text: "Hello!"} but the Inngest function in src/inngest/functions.ts expects the email field in event.data.email.
Apply this diff to align the payload with the Inngest function expectations:
- <Button disabled={invoke.isPending} onClick={() => invoke.mutate({text: "Hello!"})}>
+ <Button disabled={invoke.isPending} onClick={() => invoke.mutate({email: "Hello!"})}>Alternatively, if the intention is to send an email address, consider using a more appropriate value:
- <Button disabled={invoke.isPending} onClick={() => invoke.mutate({text: "Hello!"})}>
+ <Button disabled={invoke.isPending} onClick={() => invoke.mutate({email: "user@example.com"})}>📝 Committable suggestion

In src/app/page.tsx at line 22, the mutation payload sends {text: "Hello!"} but
the Inngest function expects an email field in event.data.email. Update the
payload in the invoke.mutate call to send {email:
"appropriate_email@example.com"} instead of {text: "Hello!"} to match the
expected structure.
