Hi, we've faced the same issue and we saw that in PharArchiver::supports the second passed argument from ArchiveManager::archive (line 100) is null.

We are also wondering why sourceType is passed if is not used?

[tubbynl]

this occurred in my CI-build where i used composer:2 as build image.

• error occurred on version 2.3.3 and 2.3.2
• error doesnt occur on version 2.2.11

i'm unsure what composer image version was used in on the original :2 version spec but perhaps this helps

my stacktrace

weird quirk in my case; it specifically failed on the tag-build, in both cases composer archive is ran identically but in the tag build the version is different (set using composer config version $CI_COMMIT_TAG)

[tubbynl]

ok; locally also reproducable when no version spec in the composer.json composer archive works; if i spec a version then it fails with the same stacktrace (using composer 2.3.3). Let me fix a example composer json file

[tubbynl]

composer.json

{
    "name": "test",
    "support": {
        "email": "github@tubby.nl"
    },
    "require": {
        "php": ">=8.1"
    },
    "require-dev": {
        "phpunit/phpunit": "^9"
    },
    "config": {
        "archive-format": "zip"
    },
    "archive": {
        "name": "test"
    }
}

composer archive
# fails
git init
git add .
git commit -m "init"
composer archive
# works
composer config version 1.0.0
composer archive
# fails

i can verify it is fixed in 2.3.4 , tnx @Seldaek !
