GHA actions are uploading source maps with dist="null" (string)

[rodolfoBee]

The recent change to support setting distribution (dist) in GHA actions introduced a couple of issues:

• If the set value is null, the file will be uploaded with the string "null" as distribution, and if an event does not have a distribution set the source map processing that relies on perfect matching release+dist will not work.

• as reported in Normalize the behaviour with dist #138, setting distribution is now required when uploading source maps. This is an optional value and should not be marked as required.

Warning from #141 still pops up when using "getsentry/action-release@v1.4.1" : /

I'm sorry @armenzg ! I deployed the wrong version of my project which still used v1.3.1

I now can confirm that the warning from #141 is gone when using v1.4.1!

Thank you : )

I confirm:

• there is no more warning for me as well
• without providing dist, the action works and it is set to none (not null).

I couldn't test whether the source map processing work without dist yet, but I imagine it does given it used to when it was none with the CLI.
Thanks!
