Do you have any modules that are printing output before the session is started?
Or perhaps some php files with blank lines before the opening <?php

This is happening for me now on 10.1 when indexing using search api:

RuntimeException while trying to render item entity:node/75890:en with view mode full for search index Search Site: Failed to start the session because headers have already been sent by "/var/www/html/web/core/modules/big_pipe/src/Render/BigPipe.php" at line 264. in Symfony\Component\HttpFoundation\Session\Storage\NativeSessionStorage->start() (line 132 of /var/www/html/vendor/symfony/http-foundation/Session/Storage/NativeSessionStorage.php).

The question was about contributed modules. Anyway, what about comment #4?

nicxvan commented

I'll check for empty lines before <?php, it's going to take a bit of time.

I don't have any module printing before the session starts that I'm aware of.

Search api is trying to render the content so I can index the rendered content so maybe that is triggering the issue.

Related issue in search api

Ok I had a chance to check, I don't see any modules with empty space before the php tag.

I think in my case it's from trying to render items to index them. I posted the related issue.

Version: 9.5.x-dev » 11.x-dev

Drupal core is moving towards using a “main” branch. As an interim step, a new 11.x branch has been opened, as Drupal.org infrastructure cannot currently fully support a branch named main. New developments and disruptive changes should now be targeted for the 11.x branch. For more information, see the Drupal core minor version schedule and the Allowed changes during the Drupal core release cycle.

The OP did not reply so this should probably be closed.

Later comments about search API strongly point to the existing issue in #15 as the main discussion area.

Sorry, do you mean that Search api has a bug in how it's render for indexing functionality?
How can we be sure the issue is there and not with BigPipe?

Okipa may not have replied, but I've experienced the same issue and responded with the requested info.

What information is the maintainer still requesting that was not answered?

Two questions I see:
Do you have any modules that are printing output before the session is started?
Or perhaps some php files with blank lines before the opening <?php

I listed all modules for that project and checked for the extra space in my project.

Version: 11.x-dev » main

Drupal core is now using the main branch as the primary development branch. New developments and disruptive changes should now be targeted to the main branch.
