How do you use Sentry?
Sentry Saas (sentry.io)
Which SDK are you using?
@sentry/nextjs
SDK Version
8.30.0
Framework Version
Next 14.2.11
Link to Sentry event
No response
Reproduction Example/SDK Setup
I have added this in tprc.ts file
const timingMiddleware = t.middleware(async ({ next, path }) => {
const start = Date.now();
if (t._config.isDev) {
// artificial delay in dev
const waitMs = Math.floor(Math.random() * 400) + 100;
await new Promise((resolve) => setTimeout(resolve, waitMs));
}
const result = await next();
const end = Date.now();
console.log(`[TRPC] ${path} took ${end - start}ms to execute`);
return result;
});
const sentryMiddleware = t.middleware(
Sentry.trpcMiddleware({
attachRpcInput: true,
}),
);
export const publicProcedure = t.procedure
.use(sentryMiddleware)
.use(timingMiddleware);
Also sentry.init is as follows
// This file configures the initialization of Sentry on the client.
// The config you add here will be used whenever a users loads a page in their browser.
// https://docs.sentry.io/platforms/javascript/guides/nextjs/
import * as Sentry from "@sentry/nextjs";
import { env } from "./env";
Sentry.init({
dsn: env.NEXT_PUBLIC_SENTRY_DSN,
environment: env.NEXT_PUBLIC_SENTRY_ENV,
// Adjust this value in production, or use tracesSampler for greater control
tracesSampleRate: 1,
// Setting this option to true will print useful information to the console while you're setting up Sentry.
debug: false,
replaysOnErrorSampleRate: 1.0,
// This sets the sample rate to be 10%. You may want this to be 100% while
// in development and sample at a lower rate in production
replaysSessionSampleRate: 0.1,
// You can remove this option if you're not planning to use the Sentry Session Replay feature:
integrations: [
Sentry.replayIntegration({
// Additional Replay configuration goes in here, for example:
maskAllText: true,
blockAllMedia: true,
}),
],
});
Steps to Reproduce
- Create a new repo with t3 stack
- add sentry
- add sentry trpc middleware
- throw a error from mutation procedure
I can only see the error that is thrown from trpc procedure with throw new Error(.....) but the inputs are not passed to sentry!
Expected Result
I expect to see the input passed on to the mutation procedure!
Actual Result
