Attachments

Sentry can enrich your events for further investigation by storing additional files, such as config or log files, as attachments.

Uploading Attachments

You'll first need to import the SDK, as usual:

import * as Sentry from "@sentry/browser";

public attachmentUrlFromDsn(dsn: Dsn, eventId: string) {
  const { host, path, projectId, port, protocol, user } = dsn;
  return `${protocol}://${host}${port !== '' ? `:${port}` : ''}${
    path !== '' ? `/${path}` : ''
  }/api/${projectId}/events/${eventId}/attachments/?sentry_key=${user}&sentry_version=7&sentry_client=custom-javascript`;
}

Sentry.addGlobalEventProcessor((event: Event) => {
  try {
    const client = Sentry.getCurrentHub().getClient();
    const endpoint = attachmentUrlFromDsn(
      client.getDsn(),
      event.event_id
    );
    const formData = new FormData();
    formData.append(
      'my-attachment',
      new Blob([JSON.stringify({ logEntries: ["my log"] })], {
        type: 'application/json',
      }),
      'logs.json'
    );
    fetch(endpoint, {
      method: 'POST',
      body: formData,
    }).catch((ex) => {
      // we have to catch this otherwise it throws an infinite loop in Sentry
      console.error(ex);
    });
    return event;
  } catch (ex) {
    console.error(ex);
  }
});

Attachments persist for 30 days; if your total storage included in your quota is exceeded, attachments will not be stored. You can delete attachments or their containing events at any time. Deleting an attachment does not affect your quota - Sentry counts an attachment toward your quota as soon as it is stored.

Learn more about how attachments impact your quota.

Access to Attachments

To limit access to attachments, navigate to your organization's General Settings, then select the Attachments Access dropdown to set appropriate access — any member of your organization, the organization billing owner, member, admin, manager, or owner.

By default, access is granted to all members when storage is enabled. If a member does not have access to the project, the ability to download an attachment is not available; the button will be greyed out in Sentry. The member may only view that an attachment is stored.

Viewing Attachments

Attachments display on the bottom of the Issue Details page for the event that is shown.

Alternately, attachments also appear in the Attachments tab on the Issue Details page, where you can view the Type of attachment, as well as associated events. Click the Event ID to open the Issue Details of that specific event.
