Is there an existing issue for this?

How do you use Sentry?

Sentry Saas (sentry.io)

Which SDK are you using?

@sentry/node

SDK Version

^9.25.1

Framework Version

No response

Link to Sentry event

No response

Reproduction Example/SDK Setup

No response

Steps to Reproduce

I am using this function to put onto s3:

export const s3put = async (key, val, options) => {
const { acl, contentType } = options || {};
const params = {
Bucket: bucket,
Key: key,
Body: val,
ContentType: contentType,
ACL: acl,
};
try {
await s3.send(new PutObjectCommand(params));
} catch (e) {
console.error('s3put got error:', e, params);
throw e;
}
const url = s3url(key);
return url;
};

Without Sentry, it works fine.

My Sentry instrument.js file is:

import * as Sentry_ from '@sentry/node';
export const Sentry = Sentry_;
if (process.env.ENV == 'prod') {
Sentry.init({
dsn: '...',
sendDefaultPii: true,
});
}

Expected Result

It should upload to s3

Actual Result

When I add Sentry instrumentation, I get this error:

            Without Sentry, it works fine.
            My Sentry instrument.js file is:
            import * as Sentry_ from '@sentry/node';
export const Sentry = Sentry_;
if (process.env.ENV == 'prod') {
Sentry.init({
dsn: '...',
sendDefaultPii: true,
});
}

            Expected Result
            It should upload to s3
            Actual Result
            When I add Sentry instrumentation, I get this error:

              Is there an existing issue for this?
              How do you use Sentry?
              Sentry Saas (sentry.io)
              Which SDK are you using?

const url = s3url(key);
