Stacktrace:

Error [ERR_HTTP_HEADERS_SENT]: Cannot set headers after they are sent to the client

code: 'ERR_HTTP_HEADERS_SENT'

Sentry initialization:

Sentry.init({
  dsn: "<actual dsn>",
});

Code that causes trouble:

      await aws.s3.send(
        new PutObjectCommand({
          Bucket: '<bucket name>',
          Key: `<some key>`,
          Body: <buffer>,
        }),
      );

package.json:

"@aws-sdk/client-s3": "^3.812.0",
"@sentry/node": "^9.24.0",

node -v:

v24.1.0

As a temporary workaround, setting tracePropagationTargets: [] solves the issue.

Expected Result

Code works well.

Actual Result

It does not.

Hi @devunt, thanks for filing this.

I tried to replicate this here but couldn't. Could you please provide a reproduction repo or try to see what's different from mine?

[mzoellner-sc]

Running into the same issue on a few projects. It looks like this was introduced in 9.23.0.

The error bubbles all the way up as an uncaught exception.

@mzoellner-sc thank you. Are you doing anything different from my attempt to reproduce here? Any chance you could share a reproduction?

[devunt]

Hi @andreiborza, My code had sent GetObject command a few lines before the issue-causing PutObject command. I'll prepare the reproduction code.
